Four symmetrical, mirrored corner mounting tabs with `1.40 mm` plated through-holes (`H1` to `H4`) extend to `33.00 mm x 37.41 mm` overall and align to the exact `29.7058 mm x 34.1132 mm` center-to-center pitch of the four 1 mm mounting posts in the watch housing.+2. **Zero-Stress FPC Ribbon Alignment**: Both bottom-contact 0.5 mm pitch ZIF connectors (`J1`: Hirose `FH34SRJ-10S-0.5SH-50` 10-pin MIP LCD connector at `X = 16.072 mm, Y = 31.210 mm`; `J2`: Hirose `FH34SRJ-4S-0.5SH-50` 4-pin frontlight connector at `X = 8.267 mm, Y = 31.210 mm`) are positioned directly on the horizontal centerlines and fold radii of the Azumo display flex tails so both ribbons plug straight in with zero sideways bend or stress.+3. **Wireless Charging & Largest Compatible LiPo Battery**: A TDK `WR222230-26M8-G` (`22.0 mm x 22.0 mm x 0.75 mm`, 26.8 uH) Qi receiver coil feeds a Texas Instruments `BQ51003YFPR` Qi v1.2 wireless receiver (5.0 V regulated output) and a Microchip `MCP73831T-2ACI-OT` linear LiPo charger configured for 100 mA CC/CV charging (`R2 = 10.0 kOhm`) into a 150 mAh `302025` standard LiPo pouch cell (`ASR00003`, `20.0 mm x 25.0 mm x 3.0 mm`).+4. **Always-On BLE 5.4 Core, Haptics & Tap Control**: A Raytac `MDBT50Q-1MV2` (Nordic `nRF52840` BLE 5.4 SoC with integrated ceramic chip antenna and 1 MB Flash / 256 KB RAM) drives the 2 MHz SPI display bus, reads hardware single/double-tap interrupts over 400 kHz I2C from the STMicroelectronics `LIS2DW12TR` 3-axis accelerometer (`0.38 uA` ultra-low-power mode), dims the frontlight LED via low-side MOSFET `Q1` (`BSS138LT1G` + `R5 = 39 Ohm`), and pulses the Vybronics `VZ30C1T8460002L` coin vibration motor via low-side MOSFET `Q2` (`BSS138LT1G`) with a `BAT54JFILM` Schottky flyback clamp (`D1`).+5. **PCBWay Manufacturing & Black-on-Black Aesthetics**: Designed to PCBWay standard design rules (`0.15 mm / 0.15 mm` min trace/space, `0.30 mm` min via drill, `1.0 mm` board thickness, 1 oz outer copper, Matte Black solder mask, and Black silkscreen).++---++## Live Fusion 360 & Engineering Gallery++### 1.
