Populated Circuit Boards

Spent today populating the circuit boards. They’re all done now, except for a couple of wires on the remote.

The remote board had no problems, aside from a couple of pins I had to jumper on the power switch. I’ve tested all the LEDs and tested the stop switch and all of them seem to work. You have to power down the remote for a couple seconds to reset the stop button.

The receiver board suffered from the same footprint issues as the breakout board, so I had to greenwire almost every pin on the connector. I haven’t had a chance to do a continuity test of them yet, but I think I fixed everything. The silkscreen for the diode was also backwards. I tested the power supply, which is good, and tested the e-stop functionality, using jumpers to simulate the xBee module. It works, even with an 84 ohm load on the TIP102 (the solenoid coil is 84 Ohms). The TIP102 doesn’t seem to be heating up at all, which is good.

Tonight and/or tomorrow I will figure out how to set up the xBee modules for I/O line passing.

I also started making the analog breakout cable for the breakout board. I still need to track down an ethernet jack for that board.
