The Badger'd SDWire3 is an improvement over SDWireC with
USB3 and SDR104 support. It can be used to automate testing sdcard interface or in 3D printing or to
create a fully remote working place. In our version of SDWire, we used USB-C interface to communicate
with host. SDWireC had a known limitation that it was only compatible up-to SDR50 speeds, with the new
SDWire3 we are enabling it to be used in new generation target devices like Raspberry Pi 5
SDWire3 allows to flash SD card connected to the DUT (Device Under Test), without physical contact with
the device. There is only one USB-C socket for connecting to host PC. Both USB mass storage and MUX
control are served through the same USB connection. The PCB board is designed in such way that it fits
into micro SD card slots. Thanks to this, there is no need for special cables with a micro SD adapter,
like in the muxPi product. It can even be used as SD card reader on steroids.
sdwire
cli tool available in PyPi provides an easy way to interact with both SDWireC and SDWire devices using
same interface.
Go to Quick Start guide to start
testing it immediately!
All the SDWire3 products that will be shipped is tested on micro SD card slot of Raspberry Pi 5 using
Gnome Disk Benchmark tool.
SDWire3 is tested and verified in house:
- SanDisk Extreme A1 - U3 Class V30 (Verified to be working with Raspberry Pi 5 [8gb/4gb])
