About the Bcam field camera PCB

Bcam field camera is an open source RP2040/RP2350 PCB design by goodmanj, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 143 × 56.3 mm, with 34 components from 5 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the Sensor_HallEffect_XYZ. By type, the board carries 25 ICs, 4 capacitors, 4 resistors and 1 module.

It belongs with the sensors designs in this gallery.

From the project

BCam Magnetic Field Camera

BCam is based on the RP2040 Raspberry Pi Pico microcontroller, the TMAG5273 Hall-effect magnetic field sensor, and the ILI9488 touch LCD screen.

BCam was originally designed as a teaching tool for physics classrooms. The documentation includes demos, lab handouts, and other teaching material.

Bcam field camera: common questions

What microcontroller does the Bcam field camera use?

The Bcam field camera is built around the Pico, from the RP2040/RP2350 family.

How big is the Bcam field camera PCB?

The Bcam field camera measures 143 × 56.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Bcam field camera?

34 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the Bcam field camera design files?

From the goodmanj/bcam-field-camera repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Bcam field camera design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Bcam field camera without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
