Mini Maestro serial baud rate limitations
On the Mini Maestro 12, 18, and 24, the following baud rates should not be exceeded, or the processor
may become overloaded, causing degraded performance.
10–100 Hz 111–250 Hz 333 Hz
Serial mode: UART/USB chained* 200 kbps 115.2 kbps 115.2 kbps
Serial mode: Dual-port 115.2 kbps 57.6 kbps 57.6 kbps
* Assuming bytes are not sent and received simultaneously, as required for the Pololu protocol.
Micro Maestro pulse length limitations (high pulse rates only).
Most servos are designed for 50 Hz operation. Unless you know that you need high
pulse rates, you can safely ignore this section.
The Micro Maestro has a restricted maximum pulse length for pulse rates of 67 Hz and higher. The
restriction depends on the Servos available setting and is enforced automatically by the Maestro
Control Center.
The maximum pulse lengths in microseconds are given below:
6 servos 5 servos 4 servos 1–3 servos
67 Hz 2448 2944 3000+ 3000+
71 Hz 2272 2736 3000+ 3000+
77 Hz 2112 2544 3000+ 3000+
83 Hz 1936 2336 2944 3000+
91 Hz 1776 2144 2688 3000+
100 Hz 1616 1936 2448 3000+
