Switch Science Releases "ESPr® Developer C5" Development Board Featuring 5GHz/Wi-Fi 6 Compatible ESP32-C5

Switch Science, Inc. (hereinafter "Switch Science"; Headquarters: Shinjuku, Tokyo; Representative Director: Shigeru Kanemoto) has released the "ESPr® Developer C5," a development board equipped with Espressif's "ESP32-C5-WROOM-1," which supports 5GHz/Wi-Fi 6.

The "ESPr® Developer C5" is a development board featuring a 32-bit RISC-V single-core processor running at 240 MHz, 16 MB of flash ROM, and 8 MB of PSRAM. It supports Wi-Fi 6, Bluetooth® 5 LE, Zigbee, and Thread. As support for the smart home standard "Matter" accelerates, the industry-anticipated support for the 5 GHz Wi-Fi band allows users to avoid the saturated 2.4 GHz band in homes, as well as interference from microwave ovens and other wireless devices, enabling more stable and high-speed communication.

The "ESPr® Developer C5" is equipped with a 3.3V regulator, various switches, a general-purpose LED, and a Qwiic/STEMMA QT connector that allows for solderless sensor connection. It is ideal for rapid prototyping of smart home hubs and edge devices. The ESP32-C5-WROOM-1 integrates a low-power 32-bit RISC-V processor that operates at up to 48 MHz. Because it can continue to operate during sleep mode, it achieves extremely high power efficiency even in applications requiring constant operation.
