WeatherPi Version 2 PCB arrived and assembled

2015-04-15 10.51.39The WeatherPi version 2 PCB has finally arrived from Seedstudio in Singapore.

I'm impressed with the "customer experience" from Seedstudio and they always seem to delivery 3 weeks after initial order.

10 PCB's came in at about £20.  To have these produced in the UK would have cost about £50 for the first one

The PCB was populated in height order.  Smallest components first working my way up to the tallest components :-

  • Surface mount LED's, Resisters and switches (painful when using a soldering iron)
  • Resisters
  • IC sockets
  • Jumper style headers
  • Molex style headers
  • 40 pin Header for connecting to Pi
  • Finally the Analogue and Digital IC's, plus the DS18B20 temperature sensor

I've gone ahead and assembled it and these are my initial thoughts:-

  • Needs mounting holes to match up with the A+, B+ and Pi 2.
  • Needs mounting holes on each corner
  • The I2c headers at the top of the board are the wrong way round.  All my other PCB's have the "head board" of the header inwards. I had to switch them round to match up with existing i2c devices I have
  • It was difficult to solder the 8 different 2 way headers for the analogue ports (on the left).  Much easier to solder the 8x2 headers for digital inputs and outputs

Next step will be testing and initial power on!
