Hi all,
I am using the Arduino Uno Q for my DIY-ECG project usually in in standalone mode Project presentation: Real-time ECG data acquisition and visualization on Arduino UNO Q - UNO Family / UNO Q - Arduino Forum.
In the setup with a USB hub and a power bank, the whole cable situation became quite messy. So I designed a small set of 3D printed parts to make the setup more compact and mechanically stable. Maybe this is useful for someone else as well.
-
Simple Baseplate
Makes the board stable on a desk. Protects the two connectors underneath the PCB with fitting slots.
-
Extended Baseplate with USB Hub Mount
Since I use a UGREEN Revodok 105 USB-C hub, I made an extended version of the baseplate that can hold the hub directly behind the Arduino.
The hub slides in and is held firmly, but can still be removed. -
Clamp for Power Bank Mounting
For my DIY-ECG project, I power the Arduino from a UGREEN Nexode Power Bank. The same power bank also runs my 15.6" Raspberry Pi HDMI monitor. So I designed an additional clamp that allows the whole Arduino + Hub assembly to be mounted directly onto the power bank.
(The DIY-ECG shield is installed in the picture).
It works surprisingly well. The power bank can even be charged while the system is running.
I uploaded the STL files to the following repository:
Best regards
