Features: Suitable for RaspberryPi2Zero GigabitEthernet Expansion Board: Supports 2Zero/ZeroW, power and communication, top pin power supply, does not occupy 10pin GPIO pins. Top pin or TypeC power supply: thePogo pin top pin connection, power supply and communication, simple and reliable The USB TypeC power interfaces can be used for power supply. RaspberryPiZero does not require further power supply. For high current output, it is recommended to use the TypeC interfaces for power supply.Size fits well without damaging the mainboard; Effectively improving circuit conversion efficiency and reducing heat generation. Pairedwith an aluminum alloy casing, the bottom and sides are designed withstripes, which is more conducive to heat dissipation. Not easy to rust The package does not include the mainboard Specifications: Item：for RaspberryPiZero GigabitEthernet Expansion Board Case Kit Supports 2Zero/ZeroW Board Material: Metal+Plastic Power current: 2.5A Power: 12.5W Power supply voltage: 5V Interfaces: USB-A Control Board Size：approx 7x5.7cm/2.76x2.24in External Case dimensions: approx 80x59x38mm/3.15x2.32x1.5in Package Includes: 1Set for RaspberryPiZero GigabitEthernet Expansion Board Case Kit note: The package does not include the mainboard Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand.
