RC Hourglass transponder v2, Attention, the reference naming of the parts is different from the original schematics on Github. Use only the list below for reference. PCB includes prog terminal at the bottom and slightly smaller footprint. Play around with C4 for best TX performance, a value around 130pF is recommended
| Name | Part | Package |
|---|---|---|
| U1 | MCP1703 or MCP1702 LDO | SOT-23 |
| C1, C6 | 10uF Capacitor | 0805 |
| C5, C3 | 20pF Capacitor | 0805 |
| Y1 | Crystal 5Mhz | Crystal_SMD |
| R2, R3 | 100R Resistor | 0805 |
| R1 | 1K5 Resistor | 0805 |
| D1 | LED LED | 1206 |
| C4 | 130pF Capacitor | 0805 |
| C2 | 47pF Capacitor | 0805 |
| U2 | PIC16F18313T-I µC | SOIC8 |
