As the snow is finally melting, I am starting to see some expired electronic vape widgets laying on the side of the road.
I picked 2 of them up, thinking I could at least salvage the battery.
When I got home and took a closer look, I realized one of them has a full color LCD. The display was shattered, but still light up on button press.
The LCD panel's model number is CT018TN01, which according to https://www.richis-lab.de/tcm_rg.htm is a 128 x 160 pixels, 65,000 colors display.
The MCU is a Nation N32G031 cortex-m0 in a 4x4 32-QFN.
Impressive amount of circuitry for a disposable product.
The other unit isn't too interesting, but does have an LED segment display.
The batteries had rated capacities of 2.96 Wh and 4.44 Wh.
