The TB9062FNG pre-driver can control BLDC motors using only a simple pulse-width modulation (PWM) input, without the need for any high-performance microcontrollers (MCUs) and software.

To solve the problem without sourcing a new switch, [Jean-Noel] built his own Arduino based Dahlander switch. This consists of three relays that select the wiring configuration for each speed mode.
