TESPuino board comes in an Arduino UNO form-factor

Apr 28, 2023 — by Giorgio Mendoza 279 views

Kickstarter featured this week an Open-source development ESP32-based board designed for learning and quick prototyping. The TESPuino provides up to 14x GPIOs, 1x MicroSD card slot for storage and 1x USB Type-C port programming and power.

It seems that there will be two TESPuino versions, however the product page mentions that the ESP32U4WDH variant has more libraries available by Espressif Systems. 


  • ESP32U4WDH — Dual Core 32-bit (up to 240MHz); 512KB RAM; 4MB Flash; 2.4GHz Wi-Fi/Bluetooth 4.2 BR/EDR, Bluetooth LE
  • ESP32-S3 – Xtensa 32-bit LX7 dual core (up to 240MHz); 512KB RAM; 8MB Flash; 2.4GHz Wi-Fi/BLE 5.0, Bluetooth Mesh

The Kickstarter page is also offering an infinity mirror and a compatible gaming controller controller equipped with x11 tactile buttons, 2x limit switches, 1x SPDT switch and 5x Neopixel LEDs. The developer of the TESPuino mentions that the controller can pair to a PC via Bluetooth, but relies on the USB Type-C port for power.
