Board Hardware
There exists multiple versions of the smartboard, see
Backside of the board can easily be removed by unscrewing the screws along the edge of the board, as well as three screws in the middle of the board.
For V1 make sure to also remove the main unit by loosening the two clips on each side and popping it out.
This will expose the electronics of the board, as well as connectors for the batteries and button.
All boards seems to use the same Texas Instruments CC2541 Bluetooth LE chip.
In the original version of the smartboard this chip can be found inside the "main" component of the board attached on the back.
Here you can see the location of the chip on a V1 board, marked in red:
In the second version of the board, the "main" component available in V1 no longer exist, and there are less visible electronics. But the same chip is used
Here you can see the location of the chip on a V2 board, marked in red:
Out of the box the board runs on 3xAA batteries (Rating: 4.5V 20mA). What I've discoverd after using the board for a while, is that once batteries start to run low on power, the detection gets drastically reduced.
To circumvent this, you can hardwire the board by unscrewing the back, cutting the red /black power wires, and solder on some longer cables. Then any AC power adapter outputting 4.5V 20mA could be added. In our board
Here is the inside of a V2 board which has longer power cable soldered on. It also has a adapter to make it easy to plug in the power adapter
