The circuit is very simple, and the breakout board already comes populated with all SMD components, so only the pin headers still need to be soldered. The assembly is both electrically and mechanically backward compatible with the first version of the RCRX2Bridge.<\/em><\/strong> <\/p>\n RCRX2Bridge II<\/strong><\/em> continues to support the two common but different control schemes used by L298N bridges: models with 2\/4-phase control and models with two logic inputs and one speed input, as well as the IBT-4 motor driver.<\/p>\n The RCRX2Bridge II<\/em><\/strong> module is connected to the receiver on the input side, as shown in the featured image.

<\/a>With the new version of the module, the width of the range in which the motor is not driven \u2014 the hysteresis \u2014 can now be adjusted via a trimmer on the circuit board (see image). This now also allows support for simpler remote control receivers whose pulse widths fluctuate by more than 5 \u00b5s in the neutral position (up to a maximum of 100 \u00b5s with the trimmer turned fully to the left). <\/p>\n<\/a>Control of bridges with two inputs<\/h3>\n
