2. Assembling the Wi-Fi Dev Board Case
The Wi-Fi Dev Board case set is designed for easy, tool-free assembly with a precise snap-fit mechanism.
- Step 1: Align the Board. Align the Wi-Fi Dev Board V1 ESP32-S2 with the back panel of the case. Ensure the four panel holes precisely match the board's mounting points.
- Step 2: Snap into Place. Target the case's flex parts precisely and apply a small force on the snap-fit joint until the board is securely seated.
- Step 3: Attach the Cap. Wrap the pins of the Wi-Fi Dev Board with the protective PC cap. This cap provides 360-degree protection, preventing accidental button presses and protecting the Type-C port from dust and oxidation. The cap can be easily put on or removed without bending pins.
