Radio Module RM1
This radio module is intended for wireless communication with free flight model. It is possible to transmit or receive data packets. The module can be connected to the Timer T10 via UART interface. Or it can works with any other timer, which has got a DT input with pull-up resistor. Furthermore, this device is able to transmit pulses of carrier frequency, so it can be used for radio tracking as a radio beacon. Communication with wireless Setuper is possible. Text messages are sending between Timer T10 and wireless Setuper over this radio module.
There are two versions of Radio Module. The Red version module forwards all received commands to the Timer. Therefore this version doesn't correspond with FAI rules and it is intended only for model testing.
The Black version module forwards only DT and EFT (Extended Flight Time) commands (other commands are ignored). For an official flight only the Black version module should be used!!!
Each user has an unique frequency channel and 32-bit address. Besides, the data packet contains 16-bit CRC checksum and finally, the whole packet is Manchester encoded. This makes the data transfer very safe.
General Features
- UART interface operation with Timer T10.
- Stand alone (no UART) operation - works only for DT command with any other timer.
- Works as a radio beacon - transmits pulses of carrier frequency.
- Transmitter power for radio beacon is adjustable by programming console Setuper 2.
Technical Specifications
- 8-bit MCU (micro controller) with 16 MHz crystal oscillator.
- Radio receiver and transmitter with GFSK modulation.
- Wide range of supply voltage from 2.3 V to 16 V. Contains 3.3 V voltage regulator.
- Frequency channel adjustable in band 430-440 MHz.
- Transmitter power 10 dBm. Receiver sensitivity -100 dBm.
- Data packet contains unique 32-bit address and 16-bit CRC checksum for safe transmission.
