| Title | TE0706-03 Under Voltage Protection Change |
| Subject | Trenz Electronic TE0706 Hardware Change |
| Issue Date | 2019-09-01 |

TE0706-03 |
Changes
#1 Replaced R31 by 953kOhm and R35 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 current drops below the under voltage lock out limit of the input protection circuit.
Impact: Undervoltage protection limit is decreased to 4.06V, which gives a larger marging for current drops 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.
