Relay 5v 4 Channel Module แบบ Low Level มี LED แสดงผล For Arduino, NodeMCU, Wemos By KPRAppCompile Support Arduino NodeMCU Wemos MicroBit Specification: 1. VCC: Power interface ,5V Low Level 2. GND: Ground 3. IN: Control interface .Drive Current at least 4mA 4. COM: Control circuit ground ,Connect to GND 5. Size: approx. 56 x 75 x 18 mm 6. Weight: approx. 52g [Features] Low level flip-flops shows that there are voltage for OV trigger mode between the signal input terminal and the ground. In a word, it is a way of short circuit trigger between signal input and GND negative pole. Please allow 1-3mm differs due to manual measurement. Due to the different display and different light, the picture may not reflect the actual color of the item. Thanks for your understanding. #relay 4ch , #relay 4channel , #relay
