A quick Google search will bring up several options for receivers based on the u-blox F9P dual frequency module but finding receivers based on the single frequency M8T receiver is more difficult. I am a regular user of the CSGShop M8T based receivers. Other than some often-counterfeit options available on Ebay or similar sites, CSGShop is the only reliable source I am aware of for M8T based receivers. CSGShop appears to have recently changed their name to GNSS OEM, but I haven’t got used to their new name yet so for this article I am going to continue to refer to them by their original name. I have been very happy with these receivers, have been recommending them for several years, and will continue to recommend them. However, I recently received a single frequency RTK capable receiver from Uputronics based on the u-blox M8 chip for review that is worth considering as an alternative.

The u-blox M8T module is based on the u-blox M8 chip combined with a crystal oscillator, flash, and several other discrete components. The photo below shows a u-blox receiver module with the cover removed. The chip in the middle of the board is the M8. In this case the module is an M8N but should look nearly identical to the M8T.
