ESP32-C3 superMINI (ESP32-C3-SuperMini)
ESP32-C3-MINI single core RISC-V MCU from Espressif
Note: this board uses the internal USB CDC interface connected to the USB-C connector for uploading.
the Arduino IDE needs to be set to reflect this. To put the MCU into upload mode you need to
press and hold the "BOOT" button, then press and release the "EN" button, finally releasing the "RESET"
after each power on.
- 4 Meg Flash
- 400 kbytes SRAM
- 15 GPIOs
- WIFI
- BlueTooth 5

ESP32-S3 proMini (ESP32-S3 pro)
ESP32-S3 DevKit:
This is my own design: a proMini type dev kit with a minimal of extraneous parts.
all pins are brought out as well as 3 headers for:
- Serial USB converter (my CP210Xx)
- USB breakout adapter connected to the ESP32-S3 native USB pins
- 3V3 regulator to drop the USB 5V to 3V3.
rev. 1.1 has 2 layout errors - has a jumper and a resistor soldered on the bottom.
chip is a WROOM-N8R2 (8 Meg flash, 2Meg pSRAM). Headers are soldered.
rev 1.2 corrects rev 1.1 errors and adds a power LED and a GP LED on pin 2 (they need to be enable via a solder pad
on the bottom), and adds a mounting hole. - N16R8 chip.

ESP32-S3 proMini - junk (ESP32-S3 pro)
ESP32-S3 DevKit: - This is a rev. 1.1 that uploads fine but after uploading all that happens is a message
"Invalid image block, can't boot" - and it reboots...
maybe someone out there can fix it.....
