Project Startup Help
Thought for 5 mins 28 sec
They’re still running. I’ll check final status once more and then give you the project links and current state so you’re not blocked waiting.
Worked for 21 sec
Created two separate PCB projects and started the split/place work in each:
- TX board: /timbochu/munkrofon-tx-pcb
- RX board: /timbochu/munkrofon-rx-pcb
Current status:
- TX clone: RX circuitry removed, board-mounted XLR replaced with compact XLR harness pads, 25 × 80 mm / 4-layer target set, placement still running.
- RX clone: TX circuitry removed, board-mounted XLR replaced with compact XLR harness pads, 25 mm width / 4-layer target set, placement still running.
- Master project remains unchanged as the system/reference design.
Open item:
- Both split-placement tasks are still running; they exceeded the wait window but are actively working on non-RF placement and verification.
Next step:
- Open each project link later to review the completed thread result, or ask me to check their status again.

Prototype Revision A Assumptions and Dependencies — Munkrofon
Status
Prototype Revision A — Not Production Validated
This file records the explicit approval to proceed with an exploratory proof-of-concept design using publicly available datasheets only while waiting for an official RF integration package.
User-Approved Prototype Scope
- Proceed with an exploratory proof-of-concept design using public datasheets only.
- Clearly identify every assumption made due to missing vendor documentation.
- Keep the RF module isolated so it can be replaced or updated later with minimal redesign.
- Follow all publicly available layout guidance from the selected module datasheet.
- Flag every location where the official reference layout may later require changes.
- Optimize architecture, analog audio path, power system, USB-C charging, battery management, balanced audio interfaces, and PCB organization.
- Generate a remaining-dependencies list before the design can be considered production-ready.
RF Module Decision for Rev A
The strongest professional ultra-low-latency DECT direction remains RTX1090 / RTX1090R1 with RTX Sheerlink/Sheersound, but the design is provisional because the complete official integration package has not been provided.
Design Rules for Rev A
- Treat all RF-module connections as replaceable interface boundaries.
- Use modular net names so a later RF module swap only affects the RF/interface block.
- Do not route or freeze RF antenna geometry as production-valid without vendor files.
- Separate power, audio, RF, and digital/debug functions in the schematic and future PCB layout.
- Mark any RF-footprint, antenna, audio-clock, firmware, or latency item as provisional unless directly supported by public documentation.
Known Assumptions
Table
| Area | Assumption | Risk |
|---|---|---|
| RF module | RTX1090/R1 public datasheet/product-sheet data is adequate for exploratory schematic structure. | Official integration guide may change pin usage, power filtering, antenna, or codec interface. |
| Audio interface | External low-latency codec/front-end will be required around the RF module. | Exact Sheerlink firmware may require a specific codec or clocking scheme. |
| Receiver output | Professional balanced XLR output requires a dedicated line driver, not the RF module directly. | Final output level/headroom may require different rails. |
| Power | USB-C 5 V charging, single-cell Li-ion, 3.3 V regulated system rails are valid for Rev A. | RF TX current peaks and charger/noise constraints need vendor confirmation. |
| PCB layout | 4-layer PCB is the preferred prototype baseline for RF/audio return paths. | Vendor reference layout may require a different stackup, antenna zone, or module orientation. |
Production-Readiness Dependencies
- Official RTX1090/R1 datasheet and lifecycle confirmation.
- Official hardware integration guide.
- Official reference schematic, PCB layout/Gerbers, stackup, and BOM.
- Official antenna layout / matching / diversity / keepout package.
- Sheerlink/Sheersound firmware, SDK, licensing, and production programming instructions.
- Numeric typical and worst-case audio latency under the intended configuration.
- External codec requirements and clocking details.
- RF test modes and regulatory integration conditions.
- Final selected battery, enclosure, antenna clearance, and mechanical constraints.
- Prototype measurements: latency, RF range, audio THD+N/SNR, noise, runtime, thermal behavior, charger behavior, and EMC pre-scan.
