- ATmega (8-bit) powered PCB V2.3d supporting individual RF modules - ATmega (8-bit) powered PCB V2.3d supporting individual RF modules
- STM32 (32-bit) powered PCB V1.0t supporting the 4-in-1 RF module - STM32 (32-bit) powered PCB V1.0t supporting the 4-in-1 RF module
The **ATmega-based board** has been designed to accept individual RF modules. This way you can select just the module or modules you want. The downside is that each module requires its own antenna. It can become cumbersome with 4 antennas protruding from the module. It is possible to soder the 4-in-1 module to the PCB using thin insulated wire. This 4-in-1 module requires only one antenna. Finally, the Atmega board has a 32k flash memory. This is big enough to accommodate more than 15 protocols, but it cannot accommodate all the available protocols.

1. A 2.4GHz antenna and pigtail For 9XR/9XR Pro, a new 3D printed module is available which makes use of the built in antenna in the handle. This means nothing is getting out of the radio back! You can find all details of this module case on [Thingiverse](http://www.thingiverse.com/thing:2050717).
1. AVR ISP programmer like the popular USBASP programming dongle that is 3.3V safe - available from many sellers on [ebay.](http://www.ebay.com/sch/i.html?_odkw=usbasp+progammer&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR3.TRC2.A0.H0.Xusbasp+progammer+3.3V.TRS1&_nkw=usbasp+progammer+3.3V&_sacat=0) There are reports that some of the cheap programmers are not safe to use with 3.3V units (like this unit). Look for USBAsp programmers with the “LC Technologies” label. {Pascal to confirm these reports are true} Also, you will need a 10-pin to 6-pin connector to connect the USBASP to the board.
