| PIN | Resistor | Serial Adapter |
| ------------- | -------- | -------------- |
| VCC | | VCC (3.3V) |
| GND | | GND |
| TX or GPIO2* | | RX |
| RX | | TX |
| GPIO0 | PullUp | DTR |
| Reset* | | RTS |
| GPIO15* | PullDown | |
| CH_PD | PullUp | |
* Note
- GPIO15 is also named MTDO
- Reset is also named RSBT or REST (adding PullUp improves the stability of the Module)
- GPIO2 is alternative TX for the boot loader mode
