About the LEDNip PCB

LEDNip is an open source STM32 PCB design by MayaPosch, published on GitHub under the BSD-3-Clause license. It is a 4-layer board measuring 90 × 100 mm, with 148 components from 45 distinct parts.

Its main chip is the STM32F427VGT6, from the STM32 family. Other key parts include the L7805, LM324, MCP2562-E-P and LAN8742A. By type, the board carries 54 resistors, 47 capacitors, 11 LEDs, 5 ICs, 5 connectors and 4 diodes.

From the project

STM32F427-based developer board with 5 channels for controlling LEDs.

LED'Nip is a 5-channel Cortex-M4-based LED controller and general STM32 development board. It has the following features:

- STM32F427 microcontroller (Cortex-M4, 180 MHz). - 100 MBit Ethernet (LAN8472A). - CAN (RJ-45 jacks). - Three 12V channels for RGB LED strips or similar. - Two channels for ~25 Watt LED panels each (5.5/2.1 mm jack) with constant current regulator (1A LDD-1000H or equivalent per channel). - 24 VDC board supply voltage. - SPI, I2C, U(S)ART, I2S and JTAG broken out into JST PH headers.

LEDNip: common questions

What microcontroller does the LEDNip use?

The LEDNip is built around the STM32F427VGT6, from the STM32 family.

How big is the LEDNip PCB?

The LEDNip measures 90 × 100 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the LEDNip?

148 components, from 45 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 LEDNip design files?

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

Can I use the LEDNip design in my own project?

Yes, under the terms of its BSD-3-Clause license, which MayaPosch chose for the repository.

Can I test firmware for the LEDNip 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.
