Description
Prototype PCB layout for a pager unit designed to operate on an existing WiFi infrastructure. It has a number of features designed for possible future expansion, to meet whatever requirements may arise during testing.
- OLED screen (0.96" OLED display with FPC connector, from BuyDisplay.com)
- DRV2605L haptic motor driver (and SMT haptic motor)
- ATECC508A crypto-authentication device
- Four soft-touch buttons intented for user interface operation
- Two soft-touch buttons intended for development and testing purposes
- Reset button
- JST connector for a rechargeable LiPo battery
- Micro USB connector for battery charging
NB: The ZIF connector (J1) is reversed in rev. A and requires some kind of mitigation, or an OLED module whose pin 1 is on the left-hand side. My OLED module’s pin 30 is on the left; there may be others that are not like this.
