ThumbsUp! Trackball v3/5, v4 Usage

ThumbsUp! Trackball comes in three versions, v3 (the bottom one), v5 (top left) and v4 (top right): https://github.com/ak66666/ThumbsUp-Trackball-v3 https://github.com/ak66666/ThumbsUp-Trackball-v4 https://github.com/ak66666/ThumbsUp-Trackball-v5-Omron Trackball v3 and v5 Versions v3 and v5 have the same layout, six mouse buttons in each, plus configuration buttons and three slider switches. The only difference between them is the switch types they use: Kailh Choc in v3 and regular mouse-type buttons Omron in v5,  These two versions can be used as thumb- or finger-operated with either left or right hand. Two slide switches define device orientation and hand it is used with: In thumb-operating mode index finger presses left button, middle finger - middle button, and ring finger - right button, this configuration is kept in all device positions (configured through switches shown above) : Trackball v4 v4 got two more buttons and it uses Kailh Choc switches. In v4 the orientation switc...

ThumbsUp! Trackball v3/v5 Assembly Steps

I designed a trackball, two versions actually, which differ in the switches used V3 with Kailh Choc switches: https://github.com/ak66666/ThumbsUp-Trackball-v3 V5 with Omron micro-switches: https://github.com/ak66666/ThumbsUp-Trackball-v5-Omron Assembly steps are quite the same, except for the switches. The original article version described v3, steps specific for v5 are added in the end. I sell the PCBs on Etsy: https://www.etsy.com/ca/listing/4367668734/thumbsup-trackball-v3-pcbs-for-dyi In this post I show the process of building the board. Bill of Materials To assemble you will need to obtain the following parts: 1x PMW3610 sensor and lens (https://www.aliexpress.com/item/1005007118767775.html) 1x Nice!nano v2 (or clone) (https://www.aliexpress.com/item/1005006074191337.html) This will give you a Bluetooth-connected device. You may add another nice!nano to make a USB dongle . 1x 34mm ball (https://www.aliexpress.com/item/1005007857787050.html) 1x 3.7V 110mAh 301230 Lithium Polymer...
