In our offer you will findESP-01 Black modulewith increased Flash memory up to 1 MB. |
Features of the ESP-01 module
Below are the features that distinguish the ESP-01 module from the entire ESP-XX family.
- It has 8 outputs:
- 3 x GPIO - digital outputs/inputs
- 2 x UART (TX, RX) - for communication with e.g. Arduino
- Installation: THT:
- Raster of the leads: 2.54 mm
- Equipped with a built-in PCB antenna
- Dimensions: 24.8 x 16 mm
Connection
The module has 8 pins, led to a 2x4 goldpin raster strip of 2.54 mm.
| Pin | Description |
|---|---|
| Vcc | Power supply 3.3 V, current consumption up to 300 mA. |
| GND | The weight of the system. |
| Tx | UART serial interface transmitter. |
| Rx | UART serial interface receiver. |
| RST | Reset system - activated in a low state. During normal operation, the high state should be given. |
| CH_PD |
Power down - when you enter a low state, you go into sleep mode. For software updates and communication via UART, the high state (3.3 V) must be given. |
| GPIO0 |
GPIO exit No. 0. To update, enter low state (connect to GND). |
| GPIO2 | GPIO exit No. 2. |
