2020-11-05BugfixesVasile Vilvoiu
* Fixed USB D+/D- switch * Added clearance at top right mounting hole
2020-11-05Small fixesVasile Vilvoiu
* Moved via that was unreasonably close to another one * Changed 13V8 diodes to SM5819PL-TP
2020-11-05Removed extra bypass cap from USB VBUS pin due to closeness to FTDI bypass ↵Vasile Vilvoiu
cap; rerouted some traces
2020-11-04Ferrite beads, hacking pads, audio fixVasile Vilvoiu
* Chose ferrite beads for IC Vcc (BLM31KN102SH1L) * Change hacking pad thickness to 0.8mm * Fixed potential oscillator when grounding audio- lines
2020-11-04Audio filtering, hackable area, miscVasile Vilvoiu
* Added bypass caps and ferrites to audio lines * Small rerouting * Hackable area * Added rev no
2020-11-03Logo and small correctionsVasile Vilvoiu
* Added logo * Connected a few unconnected pads * Fixed GND pour intersection
2020-11-03New layout, routing, misc...Vasile Vilvoiu
* Redo layout * Fixed MAX pulldown resistors on data lines. * Added jumpers in case MAX not installed. * Remove audio header * Remove some redundant solder jumpers
2020-11-02Initial footprint placement + changesVasile Vilvoiu
* Added initial placement * Remove pull-down resistors from USB lines. * Remove ferrite bead from FTDI chip as it was very close to Vcc FB * Fixed MAX TX pins * Assigned footprints. * Removed redundant solder jumpers. * Small changes for layout coherence.
2020-11-01Connector and pull down resistorsVasile Vilvoiu
* Changed back to USB-B connector. * Changed value of pull down resistors to 1k.
2020-11-01MAX driver protectionVasile Vilvoiu
* Adjust label position for readability * Protected R1OUT-R3OUT of MAX driver with OR gate
2020-11-01Filtering, jumpers, LEDs, miscVasile Vilvoiu
* Modified high level diagram to express the shared UART bus * Renamed XCVR_VCC to XCVR_13V8 * Add solder jumpers on audio, PTT and UART lines for easy prototyping/bypassing * Added bypass caps on XCVR side data and audio connectors * Add series ferite beads on data ICs Vcc * Added schottky diodes to all XCVR_13V8 * Changed series resistors of RXLED/TXLED/VccLED for 6mA current * Added power LEDs on XCVR_13V8 connector terminals * Added power LED for XCVR_5V rail
2020-11-01Fixed reversed I/O on MAX line driverVasile Vilvoiu
2020-11-01Change DC-DC convertor; other small changesVasile Vilvoiu
* Change RFM-0505S (unregulated) to PQS075-S5-S5-S (regulated) * Naming conventions * Alignment
