Following on from last months post about my SoB DB9 breakout board I’ve design a few of more SoB breakout boards using the DP5050 footprint.
The first is a 2-channel Relay Board. It has two relays with LED’s to indicate when they are active. Using it is pretty easy as it features the choice of screw terminals or pin headers to interface to it.
The next is a universal RS232 breakout. I call it universal as all the pins (8 in total but not ground) from a 9-way RS232 DB9 are broken out onto pin headers. To connect up to these are the 4 signals (T1,T2,R1 and R2) from a MAX232 (or equivalent) RS232 chip. So you can swap around the transmit and receive and handshake signals as you like.
The next board is just a classic prototyping board. There’s not much too say about this board.
The last board is a symmetric power supply for rectify AC voltage into positive and negative DC supply rails. I’m hoping to use this for a audio project I’ve got in the works.
Dangerous Prototypes (DP) have a great page describing the various PCB sizes here:
As usual you can find them on my Tindie page here
