Features
DSO138 kits are sold in two configurations. One is with all SMD parts pre-soldered (PN: 13803K, replacing 13801K).
The other is with only the main IC (the MCU) pre-soldered (PN: 13804K, replacing 13802K).
The latter serves also as a SMD soldering training kit.
For both configurations the MCU has been pre-programmed and no re-programming required.
