The RXB6 breakout board is a reliable ASK receiver with good sensitivity.
Pins
The board exposes eight pins in two groups of four pins. All pins are labeled on the front side.
| Pin | Label | Description |
|---|---|---|
| 1 | ANT | Antenna |
| 2,3,8 | GND | Ground |
| 4,5 | +5V | 3.0-5.5V |
| 6,7 | DATA | Data Out |
Many pins are exposed in duplicates. As all ASK receivers, there are essentially just three pins to connect: power supply (+5V and GND), and data out (DATA).
Make sure the power supply is properly filtered and carries no exceptional noise which could interfere and distort reception.
Antenna
There is no antenna mounted. Make sure to add an antenna or else the board will have poor reception.
For example, solder a wire to the ANT pin (17cm for 433MHz).
Technical Data
The receiver chip is covered under a metal shield plate.
