Credit card-sized quad relay board runs Tasmota firmware on ESP32 module (Crowdfunding)
The “ESP32 IoT Relay Board” is a credit card-sized ESP32 board with four small 250VAC/30VDC 7A relays that runs Tasmota open-source firmware and supports Alexa & Google Assistant for voice control. There are so many ESP32-based relay boards on the market that I don’t usually feel the need to cover new ones, but Igor Mileshin’s ESP32 IoT Relay Board is smaller than most so I thought it might be interesting to some. The smallest quad-channel relay board I’ve seen so far is the one by Seeed Studio using an STM32 MCU and solid-state relays that measures just 60 x 40mm, but the relays only support up to 2A. ESP32 IoT Relay Board specifications: Wireless module – ESP32-WROOM-32D SoC – Espressif ESP32-D0WD dual-core Tensilica LX6 processor @ 240 MHz Storage – 32Mbit SPI flash Connectivity – Wi-Fi 802.11 b/g/n up to 150 Mbps, Bluetooth 4.2/5.x LE Relays 4x “industrial-grade” relays supporting […]
