The main functions of BMS are: - To protect cells against overvoltage - To protect cells against undervoltage - To balance the cells

Smart BMS consists of four main components: 1. Cell Module (https://hackaday.io/project/181453-green-bms/log/198376-green-bms-cell-module) 2. Control Unit (https://hackaday.io/project/181453-green-bms/log/198414-green-bms-control-unit) 3. Limiter (https://hackaday.io/project/181453-green-bms/log/198378-green-bms-limiter) 4.…

Mod cell 0 02: common questions

What microcontroller does the Mod cell 0 02 use?

The Mod cell 0 02 is built around the ATtiny84A-SSU, from the AVR/Arduino family.

How big is the Mod cell 0 02 PCB?

The Mod cell 0 02 measures 62 × 42 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mod cell 0 02?

33 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mod cell 0 02 design files?

From the CHIBOY12/Ranial-Systems-BMS-project repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Mod cell 0 02 design in my own project?

The repository has no license, so all rights stay with CHIBOY12. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Mod cell 0 02 without the hardware?

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