How do the legacy RTLS1, RTLS2 and RTLS3 platforms differ?

Answer

RTLS1 is an open-source STM32 development kit for evaluation, low-level UWB work, product development and integration. RTLS2 is a closed-source deployment-oriented device with Ethernet and a web interface. RTLS3 is an open-source Arduino development kit with a lower learning barrier for evaluation and academic projects. These are platform-level descriptions. Confirm the hardware revision, firmware and delivered code/licence scope for an existing installation; the description does not imply that every connected module has open internal firmware.
