Update 03-May-2025: This project is not yet stale, just had a busy personal time. Project will be picked up again soon
Reverse engineering and tooling for the Axsem AX8052 based UU340 variant of the SES-ImagoTag Vusion 2.6BWR
for more exhaustive information about the process and results you can visit the github pages site:
ESL Modding Chronicles on github pages
- U1 - AX8052F143 - MCU + radio - 8051
- U2 - FM11NT081DS - NFC
- CN1
- both displays use IL0373 driver
- U3 - [{suspected} 1Mbit FLASH]
I'll create a markdown table with all the pin connections organized according to your requested headers.
