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 required is as follows:

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 connects the standard MiniTiouner hardware via the RPi USB port

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 10 push buttons.

There are no components to fit other than push buttons, LEDs and IR sensor (see below). The buttons are standard B3F e.g. Omron B3F-1070, RS stock number 686-6907 (Two off pack of 5) or Ebay. The sensor was Vishay TSOP2438, RS stock number 180-8012

A blank PCB is available from 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.

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.

Note that the PCB was designed for a TSOP2438 IR Sensor which has the pin connections: 1 = OUT, 2 = Vss, 3 = Gnd. Other sensors (such as the TSOP4438) have pin connections 1 = OUT, 2 = Gnd, 3 = Vss. Some sensors require +5 V supply, others require +3.3 V, but it is important that no more that 3.3 V is applied to the Raspberry Pi GPIO pin. Please check carefully before applying power!

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.

Project cases

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.

An example prototype hardware is shown here:
