V2 Gertboard photos and initial impressions

My V2 Gertboard showed up today. I promised some photos yesterday, so here they are, along with some first impressions… Main visible differences from V1 are: CE and FCC marks Different fuse holder Different motor controller chip – surface mount All ICs are soldered directly to the board apart from the ATMega, which is socketed leds are surface mount there are pull-up resistors on the buffers the buttons are surface mount the DAC chip is teeny weeny and surface mount the regulator is surface mount The jumpers with grippy extension are very practical But the […more…]

Download Python Gertboard Programs ocol – Open Collector – Darlington Array Relay Driver I’ve managed to get the open collector ocol program written in Python. The ocol program drives the Darlington Array on the Gertboard. This can be used to switch up to 6 relays, each on a separate GPIO port. I’ve managed to write versions for both wiringpi for python (ocol-wp.py) and RPi.GPIO (ocol-rg.py) They are both included in the download link, which will always contain the most up to date versions. Here’s a comparison video of Gert’s ocol program running first, then my […more…]

Assemble Gertboard photos - Tandy kit

Just finished soldering the Gertboard together. Tested the voltage and it came in at 3.34V, which is within tolerance of the target 3.3V. So, next up will be to make it do something, but I thought you should all see it now it’s done. ;) You can click any of these shots to get the full sized version. No comments about RN7 ;) I’ll stick up some assembly shots in a little bit. In the meantime, here’s the thread where people are talking about their Gertboard Assemblies. http://www.raspberrypi.org/phpBB3/viewtopic.php?f=42&t=17987

Gertboard kit is here

Not much to say about this really. I found out that Tandy had these in stock so I ordered one on Tuesday evening, and it turned up this morning. Here’s a shot of the whole kit, including, board, ribbon cable, sheet of contents and the components packed in assembly order, heat-sealed in a plastic sleeve. Good idea that! :) Looks nice. Well done Tandy. I’ll get it built when I find a slot of time. :) According to a post in the Raspberry Pi forums, Tandy has bought the boards from Farnell and made up […more…]
