Overview
The Foxbit is an ESP32 board for STEM classes and maker projects. It has Wi-Fi and Bluetooth on the chip, plus sensors and a 5x7 RGB matrix on the board, so a first project does not need extra modules. The connector is USB-C.
Features
- ESP32-D0WDQ6 dual-core, up to 240 MHz
- Wi-Fi 802.11 b/g/n and Bluetooth 4.2, including BLE
- On-board AHT20 temperature and humidity, QMI8658C six-axis motion sensor, light sensor, microphone, and buzzer
- 5x7 RGB matrix, 35 WS2812 LEDs
- 19 digital I/O, 7 touch pins, 2 DAC outputs, 13 PWM outputs
- Power from USB-C, a PH2.0 DC plug, or the gold-finger edge
