The Ryde Receiver is based around a Raspberry Pi 4. Current developments are using 2 GB memory models. Future enhancements may require 4 GB or 8 GB, but no specific requirement has been identified yet.
The hardware currently required is as follows - note this may change and you buy at your on risk!
- Raspberry Pi 4 and heatsink / fan
- 5 volt 3 amp PSU - this may be connected directly to the RPi GPIO pins, see Ryde GPIO Connections
- Sandisk Ultra 8GB+ SD card - Pre-programmed cards may be available from the BATC shop once the project is on general release
- Micro to standard HDMI converter - needed to connect the RPi HDMI output to a standard monitor
- IR receiver and remote control - see this wiki page for more details:Ryde remote controls
- MiniTiouner V2 hardware - the Ryde phase 1 hardware connects to the standard hardware using USB
Ryde GPIO connections
The only real construction needed to build a Ryde is a small GPIO PCB to connect to the RPi.
BATC has made a small daughter board - details can be found here Ryde GPIO breakout board.
The draft GPIO pinouts for the RPi4 are here: Ryde GPIO Connections
Ryde front panel
For those not using an old STB case and front panel, Mike G0MJW has designed a front panel with 9 push buttons.
There are no components to fit other than push buttons, LEDs and IR sensor and a blank PCB is avaiable fro the BATC shop https://batc.org.uk/shop/ryde-push-button-front-panel-pcb/
Most people will want to wire their own front panel with a layout that suits them, however gerber files for the above are here which should be compatible with the PCB suppliers should you so wish. The buttons are standard B3F e.g. from RS 686-6970 (Two off pack of 5) or Ebay.
Here is a 3D template
Ryde Infra Red sensors and remote controls
More details on how to add an IR sensor and what remote controls you can use is here: https://wiki.batc.org.uk/Ryde_remote_controls
There are no components to fit other than the push buttons, LEDs and IR sensor.

Video and Audio Output
The HDMI display should be connected to the primary HDMI output - that's the one nearest the USB-C port and SD Card. Audio will then be sent to the HDMI device. In this case there is no audio or video from the RPi 3.5 mm jack.
If composite video output is selected from the ssh console menu, then video (selectable PAL or NTSC) and audio is available on the RPi 3.5 mm jack and the HDMI outputs will be inactive.
There is no current configuration which will output audio on the RPi Jack whilst the HDMI monitor is in use, or that will send output to both the HDMI and RPi 3.5 mm jacks simultaneously.
Most of the early development protypes are being hosted on old STB cases - these provide a case, possibly a PSU and IR detector diode and front panel switches.
