1. Power supply requirement: 5V / 1A
Photo5 A1251WR-5P connector description
Attention: The male seat is configured in the equipment, the corresponding female seat is 1.25mm, 5P,
and the data cable is made into a twisted pair.
2.5. Module thermal design description
1. Because the product volume is too small, the chip temperature is relatively high, heat conduction
treatment is required to avoid excessive temperature to reduce product life, you can add a radiator on the
back, the radiator material is AL6063, aluminum extrusion or machining, the heat dissipation area is not
less than 100cm
²
, the surface treatment is anodized black (increasing the emissivity), the radiator
selection should avoid using long strips;
2. If the back of the customer's product is made of metal, the temperature can be directly led to the back
cover;
