About the 53xLIDAR PCB

53xLIDAR is an open source STM32 PCB design by valerionew, published on GitHub. It is a 2-layer board measuring 75.4 × 75.4 mm, with 57 components from 21 distinct parts.

Its main chip is the STM32F411RETX, from the STM32 family. Other key parts include the WS2812S, MPU-9250, KF33_DPAK and LSM9DS1. By type, the board carries 24 connectors, 22 capacitors, 8 ICs, 1 crystal, 1 diode and 1 resistor.

It belongs with the sensors designs in this gallery.

From the project

53xLIDAR is a solid state, 16 points lidar, based on ST's VL53L1x sensors

The sensors are operated by an STM32F411RE on two separate I2C buses, one for sensor 1-8, the other for 9-16. The XSHUTs are shared between two sensors on the two different I2C buses, while the sensors interrupts are separate for each sensor. For future use, there is an LSM9DS1, 9 DOF inertial sensor onboard.

The lidar outputs the data via a virtual com port from the native Micro-USB, or via a 3.3V UART on a 4 pin JST-PH connector. Power (5V 100mA) is provided through the USB or via the 4 pin uart connector.

53xLIDAR: common questions

What microcontroller does the 53xLIDAR use?

The 53xLIDAR is built around the STM32F411RETX, from the STM32 family.

How big is the 53xLIDAR PCB?

The 53xLIDAR measures 75.4 × 75.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 53xLIDAR?

57 components, from 21 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the 53xLIDAR design files?

From the valerionew/53xLIDAR repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the 53xLIDAR design in my own project?

The repository has no license, so all rights stay with valerionew. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 53xLIDAR without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
