Schematic Design Instructions:
1. H1 is the lithium battery soldering interface (no components need to be placed on the solder pad).
2. R4 is the charging current setting resistor, maximum 500mA.
PCB Design Instructions:
1. The TYPE-C housing is the touch medium and does not have a common ground
. 2. The size of the touch sensor pad needs to be designed according to parameters such as panel medium and panel thickness. 2.1 Sensing Line: On the PCB, the touch sensor pad should be as short as possible from the IC's touch input pin (sensing line). The sensing line should be at least 1mm away from copper plating or other traces, and the wire diameter should be 0.15mm~0.2mm. 2.2 Copper Plating: If there are radio signals, high-voltage devices, or magnetic fields near the touch panel, please use 20% mesh grounded copper foil for copper plating. To balance penetration and anti-interference capabilities, avoid copper plating under the touch pad as much as possible. The copper plating should be at least 2mm away from the touch sensor pad and at least 1mm away from the sensing line. 2.3 The coating on the media panel or surface covering the touchpad must not contain conductive materials or metallic components, and the entire metal casing must not be used as the sensing electrode.
Notes:
1. Acrylic thickness is 1.5mm
. 2. Battery thickness is 30 x 40 x 4 mm.
3. The reflector needs to be painted with silver spray paint to increase its reflectivity; gold is also acceptable.
4. The video shows the casing printed by my own 3D printer, made of PLA.
5. The colored version has been verified; the casing is not perfect and will be updated later.
