| If you are interested in building this, send a personal message (PM) to user //ilmenator// over at the [[http://midibox.org/forums/|MIDIbox forum]] (you have to register to be able to send PM). As of February 2020, I have PCBs (both the original TPD as well as the Euro TPD, see below) available for 10€ each, as well as a small number of kits for those having difficulties sourcing the parts themselves. Kit price for all you need to build this, i.e. PCB including every part on the BOM below, is 48€. | If you are interested in building this, send a personal message (PM) to user //ilmenator// over at the [[http://midibox.org/forums/|MIDIbox forum]] (you have to register to be able to send PM).

| The most exotic component on this board is the red/green double color dot matrix module. As the LEDs are controlled via a matrix approach, it does not really matter whether you choose common cathode or common anode modules - both will work, you'll just have to specify that in the config file. I bought mine on ebay, and they are common anode types (although they were sold to me as common cathode types!). Make sure that the pinout follows this {{:home:users:ilmenator:ysm-1288cr3g2c.pdf|duo LED matrix datasheet}}! | The most exotic component on this board is the red/green double color dot matrix module.

| Some users have reported problems when the TPD is not the last module in the DIN/DOUT chain, presumably because the are 9 DOUTs on this module, but just one DIN, which in turn leads to an unbalanced serial output, see [[http://midibox.org/forums/topic/19801-tpd-blm-16x4/|this post]]. It seems best to simply put the TPD at the end of the serial chain. | Some users have reported problems when the TPD is not the last module in the DIN/DOUT chain, presumably because there are 9 DOUTs on this module, but just one DIN, which in turn leads to an unbalanced serial output, see [[http://midibox.org/forums/topic/19801-tpd-blm-16x4/|this post]].
