27MHz remote control

This is a niche product intended for radio control (RC) purposes.  It consists of a receiver and a transmitter PCB. Both PCBs are based on the AX5043 RF transceiver. Amongst others it can be used for remote control of a model submarine equipped with piston tanks (dynamic diving).

Receiver

The receiver provides 7 digital outputs (ULN2003) and 7 proportional pulse outputs (servo control signals).

Hard- and software are derivatives of the research PCB (see elsewhere on this website). A design challenge is to make the receiver also accept signals from the Radiometrix LMT0 module (CE approved).

The power supply voltage ranges from 6 to 12VDC and can be a regulated power supply or a (rechargeable) battery.

 

Currently three prototype receiver PCBs are being tested. Upon successful completion a null series of 10 pieces will be manufactured.

Transmitter

The transmitter provides 7 digital and 7 analogue inputs. The digital inputs are on/off signals and the analogue inputs servo control signals. Optionally the Radiometrix LMT0 (RF transmitter module) can be soldered on the back of the PCB.

The transmitter PCB has a PPM input. This is intended to potentially utilize the controls (joysticks) of an off-the-shelf RC transmitter. This function requires a PPM output on the off-the-shelf RC transmitter.

Hard- and software are also derivatives of the research PCB (see elsewhere on this website). The supply voltage is 12VDC and can be a regulated adapter/power supply or a (rechargeable) battery.

Currently three prototype transmitter PCBs are being manufactured.
