ESP32-C5 Mini USB-C board supports 2.4 GHz and 5 GHz WiFi 6, up to 14x GPIO pins for IoT projects

ESP32-C5 Mini is a tiny development board with dual-band (2.4/5 GHz) WiFi 6, Bluetooth 5.x LE, and an 802.15.4 radio for Zigbee, Thread, and Matter, as well as two 9-pin headers offering up to fourteen GPIOs for IoT and Smart Home projects. It reminds me of the XIAO ESP32-C5, but it’s slightly longer and features an ESP32-C5HF4 SoC instead of an ESP32-C5HR8 + 8MB SPI flash, meaning it lacks PSRAM, and only comes with 4MB flash on-chip instead of external flash. It also adds four GPIO pins and comes with a built-in antenna and an IPEX antenna connector. NiceMCU ESP32-C5 Mini specifications: Wireless MCU – Espressif Systems ESP32-C5HF4 CPU Single-core 32-bit RISC-V processor @ up to 240 MHz Low-power RISC-V core @ 48 MHz acting as the main processor for power-sensitive applications Memory – 384 KB SRAM on-chip Storage – 320 KB ROM, 4MB SPI flash Wireless Dual-band (2.4/5 GHz) […]

SparkFun Thing Plus – ESP32-C5 board offers dual-band WiFi 6, Adafruit Feather pinout, LiPo battery support

Espressif has recently released the ESP-IDF v6.0 framework with support for ESP32-C5 and ESP32-C61, so we can expect more ESP32-C5 boards. Following the launch of boards like DFRobot FireBeetle 2 and the Espressif DevKitC-1, SparkFun has now launched its Thing Plus – ESP32-C5, an Adafruit Feather-compatible board based on the ESP32-C5. The timing is no coincidence. Although the ESP32-C5 dual-band WiFi 6 SoC was announced back in 2022, hardware makers have been waiting for stable software support. With the release of ESP-IDF v6.0, the ESP32-C5 moves from “preview” to “stable” and adds key features, such as Safe Bootloader OTA updates. This enables the ROM bootloader to fall back to a recovery partition if an update fails, making it reliable enough for companies like SparkFun to launch hardware for remote deployments and Matter-compatible smart home applications. SparkFun Thing Plus – ESP32-C5 specifications: Wireless module – ESP32-C5-WROOM-1 SoC – Espressif Systems ESP32-C5 CPU Single-core […]
