ESP32-S3-MINI-1-N4R2 Test board



This is a general purpose test/dev board with an ESP32-S3-MINI-1-N4R2 module.

  • ESP32-S3 embedded, Xtensa┬« dual-core 32-bit LX7 microprocessor, up to 240 MHz
  • 384 KiB ROM
  • 512 KiB SRAM
  • 16 KiB SRAM in RTC
  • Up to 8 MiB Quad SPI flash
  • 2 MiB PSRAM
  • GPIO, SPI, LCD interface, Camera interface, UART, I2C, I2S, remote control, pulse counter, LED PWM, USB 1.1 OTG, USB Serial/JTAG controller, MCPWM, SDIO host, GDMA, TWAI┬« controller (compatible with ISO 11898-1, i.e. CAN Specification 2.0), ADC, touch sensor, temperature sensor, timers and watchdogs

The test board has a USB-C connector for power and USB JTAG/Serial. It also has a 5 pad serial programming connection if needed. It exposes 38 GPIO pins on pads for 0.1" header pins (not GPIO26 as used internally for PSRAM). It also has a DC power connection, and a simple status LED (GPIO0).
