Thread: About 37xx converted to 34xx satellites reception accuracy

mt3328 larger in size than the NL5500. he just did not fit him.
maybe there are regional models 34xx the other revision of PSB and the chip mt3328.
test the accuracy of the coordinates is not on anything, I still find myself 3760-3490 is approximately the same. ±3m
but tomorrow I will try to do the testing under the same conditions 2-3 3760 with one revision PSB.
