 # Dingtian DT-R002
 
-A 2-channel relay board with an ESP32 and an Ethernet interface. Available direct from the manufacturer on [AliExpress](https://www.aliexpress.com/item/4001232791244.html).

-Unlike the variants with more channels, the two relays on this model are directly controlled by GPIOs and no I/O expander is used.

 When ordering this board ask for relay board with test firmware, otherwise the ESP32 will be locked.
 
-Initial programming can then be done using the [pin descriptions](https://github.com/dtlzp/relay_dev_demo/blob/main/gpio_pinout/2ch.png) and
-[pinout photo](https://github.com/dtlzp/relay_dev_demo/blob/main/gpio_pinout/debug_port_2CH_V2.png). Disconnect external power while programming.
-Connect GND and 3V3 to your programmer's power supply (which must be set to 3.3V). Connect IO1 (TX) to your programmer's RX, and IO3 (RX) to your programmer's TX.
-Connect IO0 to GND while booting to enter bootloader. Once programmed, you can perform future upgrades OTA.

 ## Basic Configuration
 
-The ESP32 naturally supports wifi, however as you've bought this relay board because it has Ethernet, the example configuration
-here enables only Ethernet and not wifi.

-If you bought the boxed version, both the LED and the "factory" button are within the box and inaccessible when closed, but are exposed in this example anyway.
