Product details
ESP32-C3-Zero (without pin header) and ESP32-C3-Zero-M (with pin header) are tiny in size with castellated holes, making them easy to integrate into other host boards. ESP32-C3-Zero comes with an onboard Type-C USB connector, which exposes most of the unused pins in a small form factor. It adopts ESP32-C3FH4 as a System-on-Chip (SoC) that integrates low-power WiFi and BLE5 with 4MB Flash. In addition, there is a hardware encryption accelerator, RNG, HMAC, and Digital Signature modules to meet the safety requirements of IoT and provide peripheral interfaces. Moreover, its low-power working mode supports most application scenarios such as IoT, mobile devices, wearable electronic devices, and smart homes. Features Low-power SoC equipped with RISC-V 32-bit single-core processor, up to 160MHz main frequency. Supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth® 5 (LE). 400KB of SRAM and 384KB ROM, and 4MB of onboard Flash memory. Castellated module and onboard ceramic antenna, allow soldering direct to carrier boards. Supports flexible clock, module power supply independent setting, and other controls to realize low power consumption in different scenarios. Integrated with USB serial port full-speed controller, 15 × GPIO pins allow flexible configuring pin functions. 3 × SPI, 1 × I2C, 2 × UART, 1 × I2S, 2 × ADC, etc. Hardware Description When using ESP32-C3-Zero with daughterboards, please avoid covering the ceramic antenna with PCB boards, metal, or plastic components. In ESP32-C3-Zero, GPIO12 to GPIO17 pins are not exposed; these pins are used for stacking the 4MB Flash. ESP32-C3-Zero uses GPIO10 to connect with WS2812 RGB LED. Please refer to the documentation link for WS2812 specifications. ESP32-C3-Zero does not employ a USB to UART chip. When flashing firmware, press and hold the BOOT button (GPIO9) and then connect the Type-C cable. The "TX" and "RX" markings on the board indicate the default UART0 pins for ESP32-C3-Zero. Specifically, TX is GPIO21, and RX is GPIO20. Hardware Connection Press the BOOT (GPIO9) key before connecting the Type-C cable each time download the firmware. Input 3.7V~6V for the castellated hole with 5V silkscreen when connecting the external power.
