MMR-70 - cheap radio module
some experiments with the fm module that features an atmega32

This will be my take on the Sony Ericsson MMR70 radio modules that feature an atmega32 on board. There are not all pins from the atmega32 broken out on the board, but for 70cents you get a decent mictrocontroller and a FM transmitter with SPI and I2C pins broken out.
My first project aims to reduce the material count from the
https://hackaday.io/project/3508-portable-trollmaster-3000 project. I have the timer2 under my control now, so I should be able to transmit morse code over radio soon.

I thought about using the Talkie library for arduino with this module, inspired by #Gas Sensor For Emergency Workers , but it is written for 16 MHz and I would have to deal with timers (again). 16MHz resonators are ordered - although I'm not certain that the atmega32L will work properly at 16MHz and 2.8V. I will look into that, but will also order 8MHz resonators as well and maybe a new LDO for 3.3v? I'm also waiting for some 2x3 pin headers for easier programming via an ISP connector and might make a labeled board... idk.
