ReflectiveSensor is an open-source printed circuit board by satomm1, from the satomm1/Robot repository on GitHub, published under the MIT licence. It is a 2-layer board of 26.5 × 6.5 mm with 7 parts on 5 nets, routed with 22 tracks and 2 vias.
It is built around the QRE1113GR. Its parts include 2 resistors, 1 capacitor, 1 connector and 1 switch. It belongs with the sensors and measurement boards of this library.
This directory contains the electrical schematic for a breakout board for the Bosch BMI323 6-axis IMU. This IMU provides a 16 bit digital triaxial accelerometer, a 16 bit digital triaxial gyroscope, and a 16 bit digital temperature sensor.
This breakout board is designed so that the IMU can be placed anywhere that is convenient.
This IMU is in a QFN package, which means the device should be reflow soldered. Alternatively, you can carefully apply solder to the PCB pads, put the IMU on top, and use a heat gun to solder the IMU.
The header pins should be soldered on the bottom of the PCB:
The assembly is meant to be installed on the robot with the IMU facing upwards. The positive X/Y/Z axes are designated on the board. The IMU should be connected via wire to the designated header on the main control board:
| IMU Breakout Pin | Main Control Board Connection |
|---|---|
| 3V3 | 3.3V |
| GND | GND |
| SCK | SCK |
| CS | CS |
| SDO | SDI |
| SDI | SDO |
| INT1 | INT1 (Currently Unused) |
| INT2 | INT2 (Currently Unused) |
The IMU connection on the main control board is indicated below:

It measures 26.5 × 6.5 mm and has 2 copper layers, 1.65 mm thick.
7 parts, built around the QRE1113GR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the satomm1/Robot repository on GitHub, at the commit this page was made from: the board is Electrical/Archives/V0.1/ReflectiveSensor/ReflectiveSensor.kicad_pcb and its schematic Electrical/Archives/V0.1/MainBoard/Buttons.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
