You can buy it back and cut the wire for use with UPD006Note: Since this yellow TYPE-C wire CC1 and CC2 have connections, if the meter is used in series, the CC1 and CC2 of the charging head will be pulled down at the same time to make the charging head enter the debugging mode and cannot work, so it is recommended to cut the wire and use it, and only connect it Just one CC UPD005 has the same function as UPD006, but the direct interface is different, and the PC configuration software is also the same (software identification is 005 model), manual and software download address:http://www.witrn.com/witrn/upd/UPD005_software.rar
