VE Lab partner brief · hardware
Chips we saved on X, photos and blueprints of the boards, the cited apps mapped onto VE projects, and a priced wishlist.
Espressif’s line is ESP32, then letter-and-number variants (S3, C3, C5, C6, P4, H2). A search for “ESP5 microcontroller” on X returned nothing. Two real things get abbreviated that way in conversation:
Scanned 1,333 bookmarks. MiniMax “M3” and NVIDIA-the-company posts are not chips. What we actually saved:
| Chip | Saves | In a bookmark as |
|---|---|---|
| ESP32-S3 | 6 | PaperMono S3R8, $15 XiaoZhi box, Waveshare 1.54″ radio, ElatoAI, LiteWing, Bitle |
| ESP32 (no variant named) | 3 | Vision guide, BitChat relay, DIY Kindle |
| ESP32-C3 | 2 | COMET air mouse; Bitle BLE node |
| Raspberry Pi (generic / CM) | 6 | Car vision, PiCarrier, retro console, plant camera |
| Raspberry Pi 5 | 1 | Gemma 4 E2B offline translator |
| Raspberry Pi 4 | 2 | Text-to-CAD case; old-phone-as-Linux roundup |
| Raspberry Pi Zero | 1 | DIY smart speaker |
| RP2040 (Pi Pico) | 1 | ¥800 flight controller |
| SX1262 | 1 | LoRa radio on Bitle (with S3) |
| MPU6050 | 1 | Gyro on the C3 air mouse |
| BMI270 / ES8311 | 1 each | On PaperMono and Waveshare boards — do not buy separately |
| Apple Silicon / NVIDIA GPU / Snapdragon | 5 / 9 / 2 | Local LLM boxes. Not on the MCU wishlist. |
Not bookmarked: ESP32-P4 / Tab5, ESP32-C5, STM32, nRF, Jetson, Hailo. Tab5 is timeline-only.
Product shots from the maker shops. Application stills from the X posts we saved. Blueprints below are kit drawings — not manufacturer CAD.
Stills from X are the posters’ own media, used here as citations. Shop photos are manufacturer product shots for partner identification — not for resale listings.
Every row is something already cited in bookmarks, here.now pages, or this week’s X. The right column is where VE can copy the pattern, not a promise we will ship it.
| Cited application | Source | Board | VE leverage |
|---|---|---|---|
| Live radio / now-playing e-paper + hold-to-talk into chat | @hot_town | Waveshare S3 1.54″ | MINY / Dank: desk object that shows the current mix, taps, or booth status without unlocking a phone. |
| Talking-face voice companion (XiaoZhi / ElatoAI) | @Piefena, ElatoAI | ESP32-S3 box ~$15 | ChipMonk + VE Lab desk: a physical agent that talks. Cloud LLM; the box is face + mic + speaker. |
| Mini Echo-class speaker (Pi Zero + ReSpeaker) | Mini Speakers sheet, Blueprint.am | Pi Zero 2 W | ChipMonk: headphone-adjacent audio object. Same job as the $15 box, Linux instead of MCU. |
| Offline Gemma translator on Pi 5 | @googlegemma | Pi 5 4GB | VE Lab demo: local model in a box. Not the Bible bot. Use the Pi 5 shopping list. |
| BitChat LoRa mesh (Bitle) | bitleproject/bitle | S3 + SX1262, C3 BLE | EventBuoy: off-grid festival / venue messaging when Wi-Fi dies. Pair with PaperMono NFC. |
| PaperMono e-ink + NFC + LoRa | M5Stack launch we bookmarked | PaperMono $65 OOS | EventBuoy Smart Labels: always-on badge/sign that also talks LoRa. Overlaps the Kindle dashboard path. |
| ESP32-S3 sensor mesh + WiFi CSI | EventBuoy workbook | ESP32-S3 | EventBuoy Venue Intelligence: already written as a beachhead idea. This catalogue is the parts list for that sentence. |
| 5″ tablet kiosk (Tab5) | X makers, not bookmarked | Tab5 $60 OOS | Partner demo / MINY artist kiosk / EventBuoy check-in: the object that looks like a product on a table. |
| Kindle → always-on e-ink dashboard | Kindle recycle guide | used Kindle $10–$30 | MINY / VE Lab walls: cheapest e-ink. No new silicon if we already have dead Kindles. |
| COMET air mouse (C3 + MPU6050) | @ebokify | C3 + GY-521 | Dank: DJ / presenter gesture pointer. Cheap experiment, not a product line. |
| Pi 5 retro console | shopping list | Pi 5 kit $180–$235 | Dank / MINY listening party: optional. Same Pi 5 as the Gemma box. |
| Pi camera → live object labels | @ardchain | Raspberry Pi + cam | Camera kiosk only if we want it. Do not copy the USB PIN-brute clips from the same firehose. |
| LiteWing ESP32-S3 drone | Alacritic bookmark | LiteWing kit | Skip unless we want aerial EventBuoy. Not in the $56 cart. |
Ranked by “can we hold it this week” then “does a bookmark or an existing here.now shopping list already justify it.” Prices are list, USD, before tax and freight. EST 29 Aug 2026.
| P | Item | Chip | List | Best place | Why |
|---|---|---|---|---|---|
| 1 | Raspberry Pi Pico W | RP2040 | $6 | PiShop.us (official US reseller). Official: raspberrypi.com | Cheapest chip we bookmarked. Flight-controller save. Ships. |
| 1 | Waveshare ESP32-S3 1.54″ e-Paper AIoT | ESP32-S3 + ES8311 | ~$30 | Waveshare official. Amazon B0FQJNW2Q5 if you need Prime. | Matches the ~$55 radio console bookmark. Add a 500 mAh LiPo ~$10. |
| 1 | GY-521 MPU6050 breakout (not SparkFun) | MPU6050 | ~$2–5 | Amazon GY-521 (packs of 5–10). Skip SparkFun list ~$30. | COMET air mouse. Pair with any ESP32-C3 mini (~$4). |
| 1 | ESP32-C3 mini / SuperMini | ESP32-C3 | ~$4–8 | Amazon or AliExpress “ESP32-C3 SuperMini”. Official Espressif devkits via Digi-Key if we need authentic silicon. | COMET + Bitle BLE node. Ships. |
| 2 | Raspberry Pi Zero 2 W | RP3A0 | $19.05 | Adafruit #5291. Same SKU as the Mini Speakers build sheet. | Bookmark: DIY smart speaker. Full BOM already published. |
| 2 | Raspberry Pi 5 — 4GB + kit | BCM2712 | $110 board · $180–$235 kit | Board: PiShop.us. Do not cheap out on the 27W PSU. Full cart is on the retro-console list. | Bookmark: Gemma translator. We already wrote the shopping list. |
| 2 | SX1262 LoRa module (868/915 MHz) | SX1262 | ~$8–15 | Waveshare SX1262 or AliExpress Ra-01S/Ra-02 only if it is SX1262 not SX1278. Match your region (915 US / 868 EU). | Bitle long-range trunk with an S3. Radio, not a computer. |
| 3 | M5Stack Tab5 (K145) | ESP32-P4 + C6 | $60 | Official shop.m5stack.com is sold out. Next: AliExpress or Amazon B0FHVKV21Y — confirm qty in cart. | The “ESP5.” Timeline, not bookmarked. Partner-demo shape. |
| 3 | PaperMono LoRa+NFC | ESP32-S3R8 | $65 | Official sold out. Notify: M5Stack. Launch AliExpress is a backup, not verified warehouse. | Bookmarked 21 Aug. Lite is $55, also OOS. |
| 3 | Freenove Ultimate ESP32 kit | ESP32 (classic) | ~$20 | Amazon (Schematik’s starter pointer). | Parts bin, not a product. Skip if we already buy S3 + C3. |
Suggested first cart (ships): Pico W $6 + Waveshare S3 ~$30 + LiPo ~$10 + C3 mini ~$6 + MPU6050 ~$4 ≈ $56. Add Pi Zero 2 W $19 if we want the speaker path. Tab5 is extra and reseller-only until M5Stack restocks.
| Job | Board | Why |
|---|---|---|
| Desk object / partner demo that looks like a product | Tab5 | 5″ 1280×720 touch, camera, Wi-Fi 6, keyboard add-on. The current “AI hardware” shape on X. |
| Always-on dashboard (radio stats, BTC, usage) | Waveshare ESP32-S3 1.54″ e-paper, or PaperMono 3.97″ | E-ink, mic, speaker, battery charging. Proven ~$55 build (Vinny / @hot_town). |
| Voice toy / “face that talks” | Cheap ESP32-S3 + screen + mic + speaker (~$15) | XiaoZhi / ElatoAI. The model runs in the cloud; the board is a face and a speaker. |
| Off-grid mesh / trail node | ESP32-S3 + SX1262 LoRa (or Cardputer Mesh Kit) | Bitle firmware for BitChat. Solar-ready. Not a consumer tablet. |
| Pocket Wi-Fi / BLE scanner | LILYGO T-Display C5 (ESP32-C5) | Wi-Fi 6, 1.9″ display. Different chip from Tab5. |
| Learn / parts bin | Freenove Ultimate ESP32 kit | What Schematik points beginners at. ~$20 + sensors for the actual project. |
Official M5Stack is empty for the boards that matter. Resellers still list Tab5. Prices below are list, not landed cost.

$65 LoRa + NFC · out of stock
Lite is $55, no LoRa/NFC, also sold out.
Proven $55 BOM
~$30 board only · battery extra
This is the board in the radio-station build we saved: Wi-Fi poll every 20s, hold-to-talk mic, e-paper “broadcast console.”
Voice / face
~$15 transparent case · AliExpress class
Screen + mic + speaker + buttons. The LLM is not on the chip. Cloud STT / LLM / TTS (XiaoZhi, ElatoAI). Polish the enclosure and the same BOM is a $79 desk toy.
Handheld
Keyboard + 1.14″ screen + battery. Mesh kit adds LoRa (Cap LoRa-1262) for Meshtastic. We already have an onboard/flash skill for Cardputer and Core-family ESP32. Mesh kit was listed backorder at M5Stack; Adv units on AliExpress.
ESP32-C5 · not Tab5
ESP32-C5, Wi-Fi 6, 16 MB flash, 8 MB PSRAM, 1.9″ ST7789. This week’s pocket Wi-Fi/BLE scanner project. Buy this only if the job is RF tooling, not a tablet demo.
The silicon is a few dollars. The product is the face, the audio path, and whoever pays the cloud bill.
These are the projects sitting in the X research file (bookmarked unless noted). They are not SKUs; they are what you put on a SKU.

| Vinny radio console | Waveshare 1.54″ S3 | Live station stats + hold-to-talk into chat. Reference implementation, not a product. | thread 3 Aug |
