SDLogger SPI Direct

The direct SPI SD Logger is originally designed to be used with the Lisa/S, but should also be compatible with other supported autopilots. It connects directly to the SPI bus of the autopilot and communicates using the SDCards SPI interface. This method is slower than when using it in SD mode, but the speed is sufficient to log IMU data at 512 Hz.
Installation
The SD Card needs to be connected to the SPI bus of the autopilot. The pinout for an SD Card is shown in the figure.
- VSS = Ground
- VDD = 3.3V
Lisa/SD
A SuperbitRF-sized PCB connects the SD card to the Lisa/S. Additionally, this PCB has pads to connect a Deltang R31d RC receiver and a molex connector for general purpose.
