- Schematic: remove holder; add BAT and BAT-; wire VBAT/GND cleanly.
- PCB: place two THT pads (1.2 mm drill, 2.4 mm pad) at edge; add +/−; keep bottom GND pour.
- Verify: confirm rules and run ERC/DRC.
Started implementing a plan
#Goal
- Replace the 18650 battery holder with two edge-mounted THT battery pads on the project. Ensure the new pads are tied to VBAT and GND with corresponding +/- silkscreen markings, while maintaining the board size at 25.0 x 12.5 mm with a bottom GND pour and full ERC/DRC compliance.
#Implementation plan
1. Schematic modifications
1. Remove the 18650 battery holder symbol from the schematic.
2. Add two THT pads labeled BAT+ and BAT-.
3. Connect BAT+ to VBAT and BAT- to GND ensuring proper net assignments without unintended merges.
2. PCB layout adjustments
1. Remove any existing 18650 footprint if present.
2. Place two edge-mounted THT battery pads on the board edge with drill size of 1.2 mm and pad size of 2.4 mm.
3. Add silkscreen markings for + (next to BAT+) and - (next to BAT-) to clearly indicate battery orientation.
4. Confirm the board outline remains 25.0 x 12.5 mm and maintain a continuous GND pour on the bottom layer.
3. Verification and rules compliance
1. Ensure design rule settings: minimum trace width 0.2 mm, clearance 0.2 mm, power net widths 0.4 mm, via 0.3/0.6 mm.
2. Run ERC on the schematic to validate net connections and then DRC on the PCB layout to ensure there are no rule violations.
#Success criteria
- The schematic does not include the 18650 holder and now shows two THT pads for battery connection, with proper labeling on the silkscreen.
- The PCB layout retains the board outline of 25.0 x 12.5 mm with an intact bottom GND pour and correct pad dimensions.
- Both ERC and DRC checks run clear with no violations reported.
Updating project description...
0:09
- Update the project description to reflect edge-mounted BAT+/VBAT and BAT–/GND pads, board size, and GND pour
- Define and save the updated system architecture diagram
- Remove the 18650 holder from the schematic
- Add BAT+ and BAT– generic THT pad symbols and wire them to VBAT and GND
- Remove any 18650 footprint from the PCB layout
- Place two edge-mounted THT pads (1.2 mm drill, 2.4 mm pad) on the board edge
- Add “+” and “–” silkscreen markings by each pad
- Verify board outline remains 25.0 × 12.5 mm and bottom GND pour
- Configure design rules (0.2 mm trace/clearance, 0.4 mm power, 0.3/0.6 mm via)
- Run ERC and DRC with no violations
- Schematic still includes the old battery holder and lacks the BAT+/BAT– pads
- PCB layout unchanged from its original state
