What is TinyBEC?
TinyBEC is exactly as it sounds - a tiny battery elimination circuit (BEC): there are many like them, but this is ours - and it's configurable too!
Occasionally customers would ask us if a RoboPad can power a 9g micro (or even a 4g sub-micro) servo, and we'd have to tell them that no, it doesn't. Servos often operate between 5 and 6 volts, with sub-micro servos requiring between 3 and 5 volts, and all pulling up to an amp of current, which we can't supply. That was until we built the TinyBEC!
The TinyBEC allows you to selectively solder the bridges on the back to get low voltage (both soldered), 4.5v (one soldered), 5.8v (the other soldered) or ~2S battery voltage (neither soldered) when supplying up to 11v input, perfect for powering a servo! It should be noted that the RoboPad still only supplies 3.3v logic signals, however we have yet to find a hobby servo that will not accept these.
The TinyBEC can be connected to your robot's power supply and will generate the configured voltage, so for a servo you can hook up its power positive and ground lines directly to the TinyBEC, then attach its signal line to the RoboPad as you usually would.
Known Issues
- Soldering the voltage selection pads is a little difficult - in the future they will be closer together and slightly smaller.
