About the MorphWatch-STM32 PCB

MorphWatch-STM32 is an open source STM32 PCB design by deebot, published on GitHub. It is a 4-layer board measuring 33.8 × 46 mm, with 63 components from 33 distinct parts.

Its main chip is the STM32L476RGTx, from the STM32 family. Other key parts include the ME6211C33M5G-N, TP4054, JDY-08 and MPU-6050. By type, the board carries 25 capacitors, 12 resistors, 6 diodes, 5 ICs, 5 connectors and 3 transistors.

It belongs with the wearables, usb & debug tools and displays & leds designs in this gallery.

From the project

The Repo contains KiCAD hardware files and software for Morph Watch

- Ultra Low Power Mode : In this mode the L476RG controller wakes up ever 1 minute to update the minutes and then sleeps. The 2 buttons are configures as external intruppts and can be pressed to wake up the controller and do other tasks like going though the Menu and getting the status of external senors or IMU data. This mode should give very long battery life

MorphWatch-STM32: common questions

What microcontroller does the MorphWatch-STM32 use?

The MorphWatch-STM32 is built around the STM32L476RGTx, from the STM32 family.

How big is the MorphWatch-STM32 PCB?

The MorphWatch-STM32 measures 33.8 × 46 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MorphWatch-STM32?

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

Where can I download the MorphWatch-STM32 design files?

From the deebot/MorphWatch-STM32 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the MorphWatch-STM32 design in my own project?

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

Can I test firmware for the MorphWatch-STM32 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.
