Changes
#1 Replaced R34 by 953kOhm and R38 by 147kOhm
Type: BOM change
Reason: Large start up currents led due to adverse conditions (e.g. weak powersupply, long wires, increased contact resistance) to a voltage drop below the under voltage lock out limit of the input protection circuit.
Impact: Under voltage protection limit is decreased to 4.06V, which gives a larger marging for a voltage drop during start up.
Method of Identification
The Serial number is written on a white QR Code sticker and placed on the top side of the PCB within the white frame. The model code and revision number (TE0706-03) are printed on the top side of the PCB above the SD card slot.
