Power Entry Stage Design
- J1:
- Type: 2-pin DC power input connector
- Function: main 5V power entry
- C1:
- Value: 10uF
- Type: ceramic capacitor
- Function: bulk input capacitor
- +5V_MAIN
- GND
-
J1 pin 1 → +5V_MAIN
-
J1 pin 2 → GND
-
C1 positive terminal → +5V_MAIN
-
C1 negative terminal → GND
- Do NOT place any additional components
- Do NOT create PCB layout or routing
- Keep schematic clean and readable
- Use proper power symbols and net labels
Establish the main 5V power input stage for the SAR acquisition system.
Started implementing a plan
#Goal
- Create the initial power-entry stage for the SAR acquisition board by adding exactly two components: a 2-pin DC power input connector (J1) and a 10uF ceramic bulk capacitor (C1), with nets +5V_MAIN and GND correctly connected.
#Implementation plan
1. Add the power entry connector:
1. Place a 2-pin DC power input connector designated as J1
2. Set pin 1 of J1 to serve as the +5V_MAIN connection and pin 2 as the GND connection
2. Add the input capacitor:
1. Place a 10uF ceramic capacitor designated as C1
2. Connect the positive terminal of C1 to +5V_MAIN and the negative terminal to GND
3. Connect the components:
1. Wire J1 pin 1 to the positive terminal of C1 using the +5V_MAIN net
2. Wire J1 pin 2 to the negative terminal of C1 using the GND net
4. Verify schematic integrity:
1. Confirm only the two components, J1 and C1, are present
2. Ensure nets are labeled as +5V_MAIN and GND and use proper power symbols in the schematic
#Success criteria
- Only J1 and C1 are present in the schematic
- J1 pin 1 and C1 positive are successfully and clearly connected to the +5V_MAIN net
- J1 pin 2 and C1 negative are successfully and clearly connected to the GND net
- The schematic remains clean and readable with proper graphical symbols for power nets
