Changes
#1 Changed micro SD card connector (J3)
Type: BOM change
Reason: Demand for industrial temperature range
Impact: Specified for industrial temperature range
#2 Changed push button (S1)
Type: BOM change
Reason: Demand for industrial temperature range
Impact: Specified for industrial temperature range
#3 Replaced input power protection
Type: Optimization
Reason: Cost savings
Impact: None
#4 Added jumper (J11) to select SD level shifter voltage on FPGA side
Type: Schematic change
Reason: Modules have 1.8 V or 3.3 V bank power where SD signals are connected
Impact: Select SD level shifter voltage according to module specification
#5 Added power switch for SD level shifter supply voltages
Type: Schematic change
Reason: Ensure power sequenzing of level shifter
Impact: Power sequenzing respected under any circumstances
#6 Replaced R5 by 1 kOhm and VBUS capacitors by 4.7 µF, add 0 Ohm resistors to OTG-ID net
Type: BOM change
Reason: Ensure USB-OTG compability
Impact: Board compatible to new version with microUSB connector and OTG capability
#7 Replaced jumpers/pin header by SMD versions
Type: Layout change
Reason: Optimize production cost
Impact: None
#8 VBAT connector fitted
Type: Assembly change
Reason: Change from THT to SMD
Impact: Connector assembled
The model code and revision number (e.g. TE0706-02 or TE0706-03) are printed on the top side of the PCB above the SD card slot.
