Regarding pinouts: With the nub up and facing you, and the pins on the bottom away from you and pointing towards your chest, from left (pin 1) to right (pin 4):

• 1) x-axis output
• 2) +5V
• 3) y-axis output
• 4) gnd

Just to make sure I’m clear, my pin 4 is the one closest to the two screw/mounting holes. When connected to an Arduino, I get a range of about 128 to 775 on each axis, with enough consistency to check if it’s at -x, center-x, +x, and -y, center-y, and +y.

The cap is removable, and is covered with a ‘sticky’ material so your thumb won’t slide off.

The pads are spaced by 2mm, but it is possible to get our 2.54mm headers connected with a bit of bending. We’re trying to get a breakout board put together. Should be available soon.
