The tiltBoard kit is a version of the tiltBoard that comes with all of the necessary parts to make the tiltBoard, but is not pre-assembled. The kit includes the parts seen in the above picture.
The tiltBoard kit can make either the 3V or the 5V version of the board. If you want the 5V version simply solder in the zener diode (Z1). If you want the 3V version of the tiltBoard, do not solder in the zener diode (Z1). That is the only difference between the two versions.
Above is the silkscreen of the tiltBoard with part names and numbers added. Solder the appropriate component to the appropriate spot on the board.
- IC1 – PIC16LF88
- IC2 – MCP4922
- IC3 – MMA6260
- R1 – 1K ohm
- R2 – 1K ohm
- R3 – 100 ohm
- C1 – 0.1 uF
- C2 – o.1 uF
- C3 – 0.1 uF
- D1 – 3.3V Zener Diode
The hardest part to solder in this kit is going to be the accelerometer (IC3). This comes in a QFN package and can be tricky to solder. I usually solder it first just to get it out of the way. Make sure the dot on the accelerometer matches up with the dot on the silkscreen of the board. Also make sure IC1, IC2, and D1 (if used) are aligned correctly on the board before soldering them.
Board Error – Jumper Needed – All Rev B Boards
When I converted my PCB files into the format needed for production one trace was left off, so a jumper will need to connect the two points together. The jumper should connect the top of C1 to pin 18 of the PIC. The jumper is seen in the picture beleow and is easy to make with a small piece of the diode lead. Sorry for the inconvenience! This error only affects “Rev B” boards.
