moteus clock synchronization
The moteus controller, when it implements its control algorithms, uses the internal RC oscillator of the onboard STM32G4 microcontroller to calculate things like velocity and to advance position over time. Typically, this is accurate to within 0.5% which is more than sufficient for most applications. However, there are cases where it does matter

ODROID-H3+ SBC review with “Unlimited Performance” mode and 2.5GbE Net Card
Hardkernel have added Intel Alder Lake mini PCs to their ODROID-H series and they are known as the ODROID-H3 and ODROID-H3+. Like the discontinued ODROID-H2/H2+, this new series also supports the Net Card which will add four extra 2.5 gigabit Ethernet ports. Hardkernel kindly sent an ODROID-H3+ together with a selection of accessories for review and I’m going to look at the effect on performance when changing the Power Limit values in the UEFI (BIOS) together with the network performance of the Net Card.
