Learning from the few mistakes I made with v0.1, I’ve just send another revision to manufacture with aisler.net!

This board includes several small tweaks.

Changed terminal connectors

I originally used simple screw terminals for the temperature probes. As I’ve figured out JST connectors and how to crimp them, I changed the PCB footprints. These fit better on the board now.

PINs for the push switch

I got the wiring of the push button completely wrong. This revision corrects that, using PINs 2 and 4.

Reverse battery terminal polarity

I swapped the positive and negative terminals on the battery connector. This is to line up with what I *think* is the standard!

What I didn’t change

Whilst I’m not 100% of my battery pad through-hole solution, I left it for now. The resistor pads are also a little small.

Truth is, using SMD pads is the correct way, but that requires hot air soldering or a reflow oven. I’m looking at a hot air stations as I’d love to move to SMD soldering for the resistors too. They aren’t cheap though and would cost me around £100 for a good entry level one.

Delivery

The boards will take about a week and a half to arrive as I opted for free shipping. The existing six I have will get made up as they are good enough for me.

Stay tuned!
