Characteristics:

1, On-board N76E003/STM8S003 and ESP-01 WIFI module
2, Having two modes:
(1) Mode 1: Cell phones carry on the wifi module directly
(2) Mode 2: Cell phone and wifi module carry on the same router
Additional function: As a USB relay module when unplugging the ESP-01
3, Transmission distance:
(1) In the open environment, the maximum transmission distance is 100m when the cell phone carries on the wifi module directly ;
(2) when the wifi module and cell phone carrying on the same router, the transmission distance depends on the router’s signal intensity;
4, Use Smartconfig technology of ESP8266 to configure the password for the
ESP-01 module with APP
5, On-board 5V, 10 A / 250 v AC 10 A / 30 v DC relay, absorb 100000 times continuously, Module with diode effusion protection, short response time
6, On-board model selection and working position indicator LED
7, On-board preserved UART debug interface and MCU program interface
8, Size: 59*40mm

Interface and sources:

  1. IN+, IN-: 5V power input
  2. TX, RX: UART communication
  3. SWIM, NRST: MCU program interface
  4. S1: Mode selection key, default is mode 1
  5. S2: Restore key
  6. LED D2 and D4(red): Relay indicator
  7. LED D7(red): Mode 1 indicator
  8. LED D5(blue):  Mode 2 indicator
  9. LED D6(green): Working state indicator, the description of D6 as below:
  10. (1) It means internal self-configuration or lost connection with the router when D6 off
  11. (2)It’s means the ESP-01 are waiting for the APP configure the password for it when D6 fast blink every 0.5S
  12. (3)It’s means the whole configuration is done and waiting to establish a TCP connection with APP when D6 slowly blink every 2S
  13. (4) It’s means the TCP connection between ESP-01 and APP is OK when D6 on all the time.
  14. Relay control command(must be format):
  15. Open the first relay: A0 01 01 A2
  16. Close the first Relay: A0 01 00 A1
  17. Open the second relay: A0 02 01 A3
  18. Close the second Relay: A0 02 00 A2
