Hi everyone,
Where is ESD3 on the BPI-R4 board? ESD3 is a NC PESD24VL1BA chip in a SOD323 package according to the schematic below:
Hi, and thank you! I see the silk screen symbol but no chip near by that easily indicates it’s a NC PESD24VL1BA chip.
NC means no soldering. The ESD model number is PESD24VL1BA.
You must have misunderstood its meaning.
Thank you for explaining the NC text. I asked an AI assistant afterwards for more info on NC and it gave the following response:
Not Connected (NC): This indicates that the component—a low-capacitance bidirectional ESD protection diode—is optional and is not populated (not soldered) on the board by default during manufacturing.
