I’ve been wanting to mess with this thing for a spell, but I couldn’t find a breakout board at the usual places, so I just up and made one. The LIS302DL 3-axis accelerometer is used in the Wii’s controller, as best as I know. Cool little 2D barcode on the chip there, huh?
It’s pretty nice — digital, SPI and TWI compatible, with a pair of interrupt signals to wake your whatever up when it sense acceleration above certain thresholds. Competitively priced with respect to the ADXL330 3-axis analog accelerometer I’ve been using. I’ve played with the LIS3LV02DQ, which is also by ST Microelectronics — this one is smaller, and a little cheaper and a much lower pin count.
Why’s it sitting on an old PCB with a clip holding it down? I got these boards done quite thin for some reason — just ’cause, I guess. Turns out the hot air I normally use to do reflow soldering just about warm up the PCB enough so it goes a bit soft. In a vice grip, it starts to warp! That’s just not good. This is my alternate jig — but, next time I’m back to the regular thickness FR4.
