We're making progress towards reading our 7 different accelerometers / IMU chips.
At the moment, we've wired up & are reading the I2C data from the following three chips:
- Kionix KX022
- Kionix KX112
- STMicroelectronics LIS3DSHTR
The ones we're still working on are:
- Kionix KX062
- STMicroelectronics LSM303AHTR
- STMicroelectronics LSM303CTR
And the 7th chip, an STMicroelectronics LIS3DHHTR, is out of stock with a 14 week lead time, so we're ruling that chip out before spending any more time on it.
Now for a walk-through of the pin layouts. The controllers are all Arduino Pro Mini boards, and the "IC"s are the respective Kionix and ST chips.
KX022

resistors are 1k Ohm
capacitor is 0.1 uF
KX112

resistors are 4.7k Ohm (1k is fine as well)
capacitor is 0.1 uF
LIS3DSHTR
![](https://cdn.hackaday.io/images/2854861532315345170.png)
resistors are 330 Ohm
capacitors are 0.1 uF and 10uF
