Accomplishments
- Reviewed the finalized NRF24L01+ wireless module datasheet and documentation to identify power, RF, and integration requirements.
- Researched antenna placement and enclosure thickness guidelines to inform the wireless enclosure design.
- Identified key power and RF considerations, including the 3.3V supply requirement, power stabilization, RF channel matching, and Wi-Fi interference avoidance.
Progress / Next Steps
- Finalized the wireless module selection and established baseline electrical/RF requirements.
- Use the identified antenna and enclosure constraints to evaluate candidate enclosure materials and dimensions.
- Next, prototype the wireless module in the proposed enclosure and validate communication reliability and range.
Deliverables
- Documented NRF24L01+ module specifications and integration requirements.
- Compiled preliminary antenna placement and enclosure design guidelines.
- Established initial wireless design constraints:
- Supply voltage: 3.3V
- Power stabilization: 10 µF capacitor across VCC and GND
- RF configuration: Matching channels between transmitter and receiver
- Interference: Avoid RF channels 2–4 due to overlap with common Wi-Fi bands
