Espressif Systems has just started mass production of the ESP32-C5 RISC-V wireless microcontroller with dual-band (2.4/5 GHz) WiFi 6, Bluetooth LE, and 802.15.4 (Zigbee, Thread) connectivity. The ESP32-C5-DevKitC-1 development is now available for about $15 on AliExpress, and should soon show up on the company’s Amazon store. So far, WiFi-capable Espressif microcontrollers have only supported 2.4 GHz WiFi since it’s cheaper and offers better range for IoT applications, but some applications may benefit from 5 GHz WiFi, so the company unveiled the ESP32-C5 dual-band WiFi 6 and BLE RISC-V MCU in June 2022. Design probably took longer than expected, but we noted documentation for an ESP32-C5 beta board in March 2024, and finally, the company has just announced that mass production has started. We’ll have a closer look at the ESP32-C5-DevKitC-1 board in this article, since it is different from the beta board. ESP32-C5-DevKitC-1 specifications: Wireless module – ESP32-C5-WROOM-1 SoC […]
