WeAct Studio ESP32-C3 Core

The ESP32-C3 processor is a single-core SoC based on the open-source 32-bit RISC-V architecture.

Arduino Board Configuration

The Arduino Board Manager supports this board by installing the esp32 by espressif package. It can be used with the following settings:

• Board: ESP32C3 Dev Module
• Upload Speed: 921600
• USB CDC On Boot: Enabled
• CPU Frequency: 160 MHz
• Flash Frequency: 80MHz
• Flash Mode: QIO
• Flash Size: 4MByte (32Mbit)
• Partition Scheme: Default 4MB with spiffs (1.2MB App/1.5MB SPIFFS)
• Core Debug Level: None
• Erase All Flash: Disabled
• JTAG Adapter: Integrated USB JTAG

Momentary Buttons

There are 2 momentary buttons on the board. 1 of them is pulling the BOOT GPIO09 pin to ground and one is connected to the EN and will reset the processor.

Boot = IO9 Reset = Chip_EN

There is no external pull-up resistors on the board so the internal pullup resistors of the ESP32-C3 must be enabled.
