1. Fully compatible for models that have the 40-pin GPIO header (4, 3, 2, B+)2. Supports the following brand M.2 5G Modules: for Quectel: RM500Q RM500U; for Gosuncn: GM800; for : SIM82003. Compatible the following brand Boards: for 4, 3, 2, B+; for Tinker Board; for Rock 64*; for 's board; for Latte Panda4. Clip-in M.2 socket compatible with worldwide LTE, UMTS/HSPA+ and GSM/GPRS/EDGE coverage with regional or global modules which work with different frequencies & carriers5. MANO SIM Card socket can easily reachable on the upside of the HAT. Efficient and low quiescent current power circuit can to 3AmpsProduct name: M.2 expansion card for Working temperature range: -40C ~ 80CProduct size: 85 x 56mmNote 1: The Base HAT doesn't need driver. Rather The host computer(such as RPi, Tinker Board) needs the driver of the compatible module that will be used with the Base HAT. For example, if you are using Quectel's EC25 with the Base HAT, then your host device should have the driver for Quectel EC25. Nowadays, most of the Linux comes with the required drivers installed as a result the modules are recognized.Note 2: These compatibility list created by assuming you've connected the Base HAT to the device via USB. UART communication can be work with every device in the list easily which have 3.3V level UART port.color:BlackMaterial:PCBPackage Contents:1 x 5G/4G&LTE Base HAT1 x USB 2.0 to TYPE C Cable1 x USB 3.0 to USB 3.0 Cable1 x Screw Driver8 x copper nut8 x M2.5 screwOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
