Some of our products, particularly our EtherMega contain a top loading SD card holder. Unfortunately top down SD card holders can be quite unintuitive to use as they operate in quite a different fashion to traditional holders.
We have put together some instructions to help you master using a top loading SD card holder in no time! Check out the instructions at the following link to get started.
The EtherMega is a great “fully-loaded” Arduino-compatible board. Apart from being completely Arduino Mega2560-compatible, it includes a full Ethernet interface, a microSD card socket, full USB interface, optional Power-over-Ethernet support and still has a circuit prototyping area with extra I2C interface pins. So if your project is breaking the limits, upgrade to the EtherMega today.
