Product description:

This product is a complete RF transceiver including the data link layer in one module.
The module can transmit and receice data with a data rate between 150 bit/s and 115.2 kbit/s. Every data rate between 150 bit/s and 115.2 kbit/s is possible, even non-standard data rates. The RF data rate, bandwidth and packet size are automatically adjusted to the UART data rate.
The transceiver module has an efficient transmitter with a very high output power.

To make a transparent serial RF data link, you need two modules.

Possible settings:

- RF power
- Address
- AES-code
- UART data rate


The encryption of the data is solved in the microcontroller in stead of in the RFM69HCW RF module. This is to prevent the AES code to be read when the circuit is powered up. 

* under specific conditions:
The range depends on the following parameters:
- TX power
- UART data rate
- Antenna height
- Antenna type
- Etc.

Download upgrade: download the .txt file and rename to .hex.
