ESP32-C6-Zero-B
The ESP32-C6-Zero-B is a compact microcontroller development board that integrates multiple digital interfaces and supports a wide 5-36V power supply.
On the hardware side, it uses the ESP32-C6FH8 chip, featuring a 32-bit RISC-V high-performance processor (HP Core) running at up to 160 MHz and a 32-bit low-power coprocessor (LP Core) running at up to 20 MHz. The chip comes with 8 MB Flash, 320 KB ROM, 512 KB HP SRAM, and 16 KB LP SRAM, making it easy to expand various peripherals.
On the software side, it supports development with the ESP-IDF framework or Arduino IDE, allowing quick prototyping and deployment in actual products.
