CoreData Global, a Singapore-based research and development firm, has just introduced the RelayFi 4-channel relay board based on ESP32 and compatible with Tasmota open-source firmware, as well as Espressif’sESP RainMakercloud andESP-NOWnetworking API. RelayFi is fitted with an ESP32-WROOM-32...
The 4-Channel SPDT Relay HAT for Raspberry Pi utilizes four high-quality SPDT (single pole - double throw) relays and provides NO/NC (Normally Open/ Normally Closed) interfaces that can control the load of high current. This means it could be a nice solution for controlling devices that can...
Grove - 4-Channel SPDT RelayThe Single Pole Double Throw SPDT relay is quite useful in certain applications because it has one common terminal and 2 contacts which are great for selecting between two options. The Grove - 4-Channel SPDT Relay has four single pole - double throw (SPDT) switch...
Note that, one of the five LEDs (D5) in the YL-70 module is the power supply indicator and the rest (D1 to D4) are signal indicators. Each signal LED illuminates as its corresponding channel output goes to a LOW state. Below is the schematic of the YL-70 module I got from the ...
