Description
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
