About the Scbs pico PCB

Scbs pico is an open source RP2040/RP2350 PCB design by CoolNamesAllTaken, published on GitHub. It is a 2-layer board measuring 60 × 60 mm, with 50 components from 28 distinct parts.

Its main chip is the SC0915, from the RP2040/RP2350 family. Other key parts include the TLV9062IDR and BPC-817S ( C BIN ). By type, the board carries 29 resistors, 9 capacitors, 4 transistors, 3 ICs, 3 diodes and 2 connectors.

It belongs with the power & battery designs in this gallery.

From the project

Single Cell Battery Simulator for testing a BMS.

Cellsim 4S is a low-current battery pack simulator that simulates four battery cells in series. Each cell has a settable output voltage between 2.5-4.5V and a readable output current. Communication is done over a 9600 baud UART link using a custom serial protocol.

SCBS Pico is a single battery cell simulator that can be daisy chained with other devices of the same type in order to build a full simulated battery pack. It is the basic building block of the CELLSIM 4S.

Scbs pico: common questions

What microcontroller does the Scbs pico use?

The Scbs pico is built around the SC0915, from the RP2040/RP2350 family.

How big is the Scbs pico PCB?

The Scbs pico measures 60 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Scbs pico?

50 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Scbs pico design files?

From the CoolNamesAllTaken/scbs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Scbs pico design in my own project?

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

Can I test firmware for the Scbs pico 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.
