Do I need to download any board definition files for Arduino?

No. You can select the Arduino Mega 2560. This board is identical, pin wise, to the official Arduino Mega.

You could use the Wiring definitions as well, but there is no need. The links above are fixed.

I should be more specific. If you are using an external SIM card holder, then you can connect 3.3V or 1.8V to SIMVDD. But if you are using the on board SIM on the ADH8066, then I don’t think you need to mess with that pin.

This board outputs the temperature data through the TX serial line (on the atmega), so you can read it with either another uC or the FTDI Basic. You should be able to plug the board into a 3.3V or 5V FTDI Basic and immediately see temperature data streaming in a serial port at 38400.

You will need to supply voltage on the SIMVDD pin. See schematic.

I’d suggest using break away female headers. I added them to the related items.

Yes, although you will need a RS232 to UART converter.

Here is the part number: CSTCE8M00G55-R0

It’s available on Digikey.

Yes, you are correct, the Rsense resistors are not 1 watt. In an upcoming revision, we will correct this. However, the 2-layer layout prevents the board from running at 2A anyway. In other words, you will hit thermal shutdown at about 1A per motor driver due to the layout and the Rsense resistors that are currently on the board are fine for 1A.

Make sure you are connecting the motor winding correctly to the board. Each winding should give you less than 10 Ohms on a ohm meter and each winding is connected to each pair of headers, for each channel. So for the motor you are using, there will be two pairs going into channel one, and each pair will have a very low resistance.

Also, try adjusting the trim pot.

Sorry about that, those things are somewhat delicate.

You can short across the terminals and feed 5V directly into USBVCC (be sure to look at the schematic/eagle files or find the right pins with a DMM). Then your android will want to take a full charge though and will drain a small battery pretty fast.
