Equipped with a RISC-V 32-bit single-core processor, ESP-C3-13 is a highly integrated low-power Wi-Fi and Bluetooth system-on-chip (SoC). The ESP-C3-13 development board is a core development board designed with the ESP-C3-13 chip. This development board continues the classic design of the NodeMCU development board, leading all I/O to the pin headers on both sides, and developing Users who can connect peripherals according to their needs. It has industry-leading low power consumption performance and radio frequency performance supports Wi-Fi IEEE802.11b/g/n protocol and BLE 5.0, supports secondary development. It is designed for the Internet of Things (IoT), mobile devices, wearable electronic devices, and various applications such as the smart home.
