Lot No.
Table 1 Pin definition
For 8258 chips with lot No. of EP5682.20 (VID=0x01, 1827 ≤ Data code < 1844), since PC2 is pulled down by an
internal diode, all of its functions cannot act normally.
For 8258 chips with lot No. of EP6070.20 (VID=0x03, Date code≥1844), PC2 function bug has already been fixed.

2.1 Supply power
There are two methods supported to supply power for the TLSR8258 Dongle.
1) Supply power via battery:
Connect PIN1 and PIN3 of J6 with GND and 3.3V of power, respectively.
Note: There is no need to connect any header with jumper cap. Make sure the
cap is removed from J8.
2) Supply power via USB interface:
Make sure one jumper cap is connected on J8 of TLSR8258 Dongle.
Connect the USB interface of the TLSR8258 Dongle with PC USB.
