The remote and control boards for BD1 should make cabling easier and possibly offer a little more functionality.
Basically, the wiring is similar to the original wiring.
Important differences is the optional support of a Bluetooth connection between the remote board and the control boards.
Or wired as standard via the “remote” labeled pin strip.
BD1 Remote board:
The buttons and joysticks are attached via pins or can also be soldered on.
4x buttons (B1-B4)
4x switches (SW1-SW4)
(Whereas technically there is no difference between button and switch)
6x Potentiometers (Pot1-3 & Pot X-Y)
The board requires 5V and the code runs through an Arduino Nano.
Optionally, an HC-05 Bluetooth module can be attached.
BD1 Mega Shield:
The Mega Shield sits on top of a regular Arduino Mega2560.
The remote control can be connected via the controller.
Or it can also communicate with the board via Bluetooth.
It would also be technically possible to control everything via a mobile phone, provided you have a code.
Otherwise, all controls (apart from the joystick) can be connected directly.
In addition, there are T1-T6 as pins. These would be e.g. suitable for touch sensors.
Further features would be an onboard DF player with lineout via jack socket and terminals or a direct connection of small loudspeakers.
The board can forward the input voltage to the amplifier via AMP OUT.
BD1 Nano Shield:
The Nano board is more compact and has fewer inputs than the Mega Shield.
It is intended to be controlled exclusively with remote control or via smartphone.
Further features would be an onboard DF player with lineout via jack socket and terminals or a direct connection of small loudspeakers.
BD1 ESP32 Controller:
The ESP32 board is mostly experimental and aimed at experienced builders.
