ER-TFT028A3-4

EastRising/BuyDisplay raw 2.8-inch 240x320 IPS TFT LCD panel, ST7789V controller, no touch, 50-pin 0.50 mm FPC, parallel/RGB/serial interfaces, nominal 2.8 V VCI/VDDI and approximately 70 mA white LED backlight.

The verified display interface, 2.8 V translation, charger limits, and GPIO remap are in place. Two hardware items remain blocked by missing authoritative geometry/electrical data—the IMU footprint and backlight LED string—so I’m independently checking the completed schematic and documentation before closing.

Worked for 2 mins 55 sec

flux

Implemented the verified ER-TFT028A3-4 50-pin display interface, 2.8 V supply and level translation, 8-bit I80 GPIO mapping, and safe BQ24074 500 mA/349 mA charging configuration. Final ERC, passive, and schematic-readability checks are clean; no PCB layout work was performed.

Remaining blockers

LSM6DS3TR-C: authoritative LGA-14 land-pattern geometry was not accessible, so no footprint was guessed.
Backlight driver: the panel documentation does not provide sufficient LED string forward-voltage/topology data; BL_PWM is reserved but the power stage remains intentionally incomplete.
Future USB-C advertised-current detection remains unpopulated; this revision is safely locked to 500 mA.

Updated files: Project Specification, Block Diagram, Firmware Getting Started, and Board Bring-Up Plan.
