We have a product that utilises the XM1110\_1103886 configured to obtain location based on GPS and Galileo constellations using the UART interface. As the part is now end of life we are looking to undertake a last time buy stock purchase of an alternative to cover spares and repairs. The XM1110\_1104311 in stock at Digikey has the same hardware footprint. Can you clarify the XM1110\_1104311 firmware and functionality differences compared with the XM1110\_1103886 ?

Additionally could you please clarify the constellation coverage of the XM1210\_1104263, having the same footprint, connectivity as the XM1110 but requiring a different software driver.
