4 2015-01-12 fabian althaus We have designed the new SODAQ Mbili (which means Two in Swahili) with all the input we got from our early adopters. What’s so great about the Mbili? 1284P Microcontroller The Atmega 1284P is the ‘big brother’ of the 328P. It has all the memory and program space you have been hoping for. 128kB flash for your programs (that’s 4x more than the 328P) 16kB memory (that’s 8x more!) It’s still a picopower chip, so it is ideal for low (solar) power applications. You can still program it with the Arduino IDE. The bootloader has been patched and the hardware files are available. Just recompile your sketches and you are ready to go. sodaq mbili http://mbili.sodaq.net/ rev4 sodaq mbili ATmega1284P microcontroller board (sodaq) Sodaq Mbili (Rev4) 3.3V

Pin 2 on the bee slot is connected to Serial1 (RXD1). With a solder jumber this can be changed to Serial (RDX0)

Pin 3 on the bee slot is connected to Serial1 (TXD1). With a solder jumber this can be changed to Serial (TDX0)

Pin 4 on the bee slot is normally not connected

Pin 6 on the bee slot is normally not connected

Pin 7 on the bee slot is normally not connected

Pin 8 on the bee slot is normally not connected

Pin 9 on the bee slot is connected to D23 and is used as DTR pin to switch bee modules on and off or enable sleep

GND

Pin 11 on the bee slot is normally not connected

Pin 12 on the bee slot is connected to D8 and is used as CTS pin to indicate if the bee module is ready

Pin 13 on the bee slot is normally not connected

Pin 14 on the bee slot is normally not connected

Pin 15 on the bee slot is normally not connected but by using solder jumper it can be used to connect to pin A7

Pin 16 on the bee slot is connected to D9 and can be used for the RTS signal

Pin 17 on the bee slot is normally not connected but can be connected to the MCU RESET pin by making solder jumper SJ7

Pin 18 on the bee slot is normally not connected

Pin 19 on the bee slot is normally not connected

Pin 20 on the bee slot is normally not connected but by using solder jumper it can be used to connect to pin A7 for the Ring Indicator signal
