Bluetooth Circuit Design Modifications
Thought for 2 mins
I recommend adding the following parts to implement your simplified analog/Bluetooth/USB design.
Table
| Part Name | Purpose | Manufacturer Part Number | Quantity | Footprint | Datasheet Link |
|---|---|---|---|---|---|
| Terminal (single pin) | Board I/O connection for analog inputs A0–A7, power rails, VIN, 5 V, 3.3 V, and GND | 835bf3e1-33dd-41bb-a166-c0a31607d645 | 13 | Through Hole 2.54 mm | ___ |
| USB-C Connector (24-pin) | USB power and data interface | 2024100002 | 1 | Right-angle SMTA | |
| HC-05 Bluetooth Module | Wireless serial link (UART ↔ laptop serial monitor) | HC-05 | 1 | 12.7 mm×27 mm | |
| 10 kΩ 0603 Resistor | Ground-sense series resistor on one GND terminal | 5687faf7-59c1-4185-87b6-d9a4cbf1f0a7 | 1 | 0603 |
