BLE ESL Board Design


Created the datasheet-backed CH592F QFN-28 component and completed the 42-component schematic with dual isolated CR2450 cells, BLE RF/clock/debug circuitry, and SSD1680 E-Ink logic interface. The external 15 V converter was removed; final ERC and passive checks report no open issues.
Open item
  • The panel datasheet image does not clearly expose two charge-pump diode junctions, so D4/D5 remain intentionally unconnected. The design is not ready for PCB release until confirmed from a clear GDEY0213B74 reference schematic.
Next steps
  1. Provide a clear panel reference schematic or manufacturer application circuit to finish D4/D5.
  2. Review the schematic pin assignments.
  3. Proceed to PCB sizing and component placement once the bias circuit is confirmed.
Please find a clearer GDEY0213B74 reference schematic and finish the D4/D5 charge-pump wiring.
I’ll locate an authoritative or clearly legible GDEY0213B74/SSD1680 reference circuit, resolve the exact D4/D5 junctions, update the schematic, and re-run connectivity/ERC checks.
I prepared the research-and-fix plan, but execution stopped because no ACUs are currently available. The schematic remains unchanged: D4/D5 are still intentionally unconnected, and no guessed charge-pump wiring was added.
Remaining work:
  • Locate and cross-check a clear official GDEY0213B74/SSD1680 reference circuit.
  • Wire and orient D4/D5.
  • Verify the complete bias network and rerun ERC.
  • Update the specification and bring-up plan with the sourced topology.

Schematic of CH592X BLE E-Ink ESL

Schematic is Auto-placed

The schematic has been arranged automatically. Flux can redraw it to be more readable, with components placed in related groups and wires drawn more legibly. This takes about 10-60 mins.
