I happened to damage/desolder few components near the TF card, can just get to know the values for it so i can bring up the board back

[tangzz-radxa]

Hi, sorry to hear about the damage. The component values around the TF (microSD) card are all published in the official schematic PDFs on the Zero 3 download page:

• ZERO 3W V1.11 schematic: https://dl.radxa.com/zero3/docs/hw/3w/radxa_zero_3w_v1110_schematic.pdf
• ZERO 3W V1.12 (AIC8800 version): https://dl.radxa.com/zero3/docs/hw/3w/radxa_zero_3w_v1.12_schematic.pdf
• ZERO 3E V1.2 schematic: https://dl.radxa.com/zero3/docs/hw/3e/radxa_zero_3e_v1200_schematic.pdf

Look for the "MicroSD Card" sheet. On ZERO 3W V1.11 (sheet 16) and ZERO 3E V1.2 (sheet 19), the parts near the TF connector are:

• Series resistor on the VCC3V3_SYS feed: R90723 = 0R
• Decoupling capacitor: C227 = 100nF / 10V
• ESD protection arrays on SDMMC0 data/CLK/CMD lines: D13-D19 = BTR04G02
• Card detect: on 3W, Q3 = MMBT3904M with R137 = 10K and R138 = 10K (R90731 = NC); on 3E, R137 = 0R on the DET line
• TF connector: 3W = TFP09-2-12B, 3E = HYCW104-TF08-375B

Please confirm whether you have a ZERO 3W or 3E (and the PCB revision printed on the board), then use the matching schematic. The component placement maps in the same download section can help you identify the exact reference designators of the parts you desoldered. If you tell us which board and which component(s) were affected, we can double-check the values for you.

I have radxa Zero3W and ther PCB version is V1.12 ,
the schematics is available but there are no designaort printed on the board by which we could confirm the right component,
ther damages components are placed exactly on the right side of the TF card, near the 40 pin GPIO header
if the board is placed in a why that the TF card is on top the CSI camera connector in bottem and the 40 pin header on the right side of the board,
i am looking for the componentes places between the TF card and the Header,
2 Cap on the top
one tiny resistor placed vertical,
a transistor below them again 3 CAP placed and 2 tiny resistor near the header ,
i can provide you the image for it if i get any mail id or point of assistance over chat

Hi, Sorry for the late reply. Please refer to the component placement diagram for version V1.11, as it is the same as version V1.12.
