Introduction:
Based on Essence's official RA series customized adapter board, all pins are lead out.
Supported models:
| RA-01 |
| RA-02 |
| RA-01H |
| RA-01S |

Design Points:
The LOD regulated output is 3.3V, and the input can be 5V or 3.3V. The choice of power supply is more flexible.
When choosing EDS protection devices, you can choose EDS electrostatic protection according to your personal needs.
Choose 433Hz for the antenna, which has a longer distance. There are two 100nf capacitors in the antenna part, which can be used without soldering to enhance the signal strength in the future.
