A whole Wi-Fi and Bluetooth computer on a board the size of a postage stamp. The ESP32-C3 gives you a 32-bit RISC-V core at 160 MHz with 4 MB of flash and 400 KB of SRAM, 802.11 b/g/n Wi-Fi and Bluetooth 5 LE, and native USB-C for programming - all in 22.5 x 18 mm with castellated edges you can reflow onto your own PCB. Deep sleep is around 43 microamps, so it suits battery-powered sensors where a full ESP32 board simply will not fit.
Key features
- 22.5 x 18 mm with castellated, solder-down edges
- RISC-V single core at 160 MHz, 4 MB flash, 400 KB SRAM
- Wi-Fi 802.11 b/g/n and Bluetooth 5 LE
- 13 GPIO, 6 ADC channels and 6 PWM channels
- Native USB-C - no separate serial chip
- About 43 uA in deep sleep, good for battery sensors
- 3.3V logic only - 5V on a GPIO pin will damage it
