[CNX-Software] - ELLO LC1 – A 2mm thin DIY “computer” based on Microchip PIC18 8-bit MCU

We often write about business card or credit card-sized boards, but it’s only true for 2D dimensions, as most boards are over a centimeter thick, with possibly the thinnest we’ve covered being the Khadas Edge2 SBC that’s just 7mm thick. So Kn/vD took it upon himself to build a DIY computer that was really about the size of a credit card, and came up with the ELLO LC1 based on a Microchip PIC18 8-bit microcontroller, featuring an integrated display and keyboard, and powered by a coin-cell battery. It’s just 2mm thin. ELLO LC1 specifications: MCU – Microchip PIC18 (PIC18F47Q83-I/PT) 8-bit microcontroller with 13KB RAM and 128KB flash, out of which 64KB are reserved as user file storage Display – 20×4 character text panel (Display Visions EADOGM204N) Keyboard – 48x touch panels on the PCB Expansion – 12-pin unpopulated header for debugging (ICSP) and GPIO expansion Misc – Power button Power [...]
