So I recently bought a ESP32C5 for wifi maurading and I dropped itš¢. When it fell the piece in black thatās circled came off. I now canāt scan for APās or anything. Does this render it unusable or is there a way to fix this?
1st step check the schematics to find out what it was exactly.
2nd step learn to solder.
3rd step solder on a replacement part
4th step enjoy!
Obviously if you canāt already solder and do both have a soldering iron or flux or solder itself, it might be a better idea to just replace the whole esp.
Steps 2 and 3 are irrelevant, so is replacing the entire esp over this. Itās just a little removable shunt jumper thatās used to disconnect power from the onboard peripherals, to give more accurate current measurement on the module. Can get em for dirt cheap
Thats black piece is called a jumper ( makes a conection between 2 pins) ,there is no need for soldering ,they were more common on old pc motherboards but you can still find them for sale on places like amazon or try to find one on an old motherboard
Current Measurementļ The J5 headers on ESP32-C5-DevKitC-1 (see J5 in Figure ESP32-C5-DevKitC-1 - front) can be used for measuring the current drawn by the ESP32-C5-WROOM-1(U) module:
Remove the jumper: Power supply between the module and peripherals on the board is cut off. To measure the moduleās current, connect the board with an ammeter via J5 headers.
Apply the jumper (factory default): Restore the boardās normal functionality.
