What’s inside

Closed design

NanoRFE states in writing that the V2.3/V2.4 (Plus4/Plus4 Pro) hardware design is confidential and proprietary and reverse engineering is forbidden; nothing is published for this exact revision.

Research notes

nanorfe.com/nanovna-v2.html explicitly states 'V2.3 and V2.4 designs are confidential and proprietary, and reverse engineering is forbidden' (confirmed via WebFetch), and an official reply on the NanoRFE forum thread 'Nanovna v2 plus 4 main board schematic' says 'We do not have public schematics for newer hardware versions like the V2 Plus4.' The older, unrelated V2.2 (S-A-A-2) design is open (github.com/nanovna-v2/NanoVNA2, gEDA schematics + Gerbers + BOM under CC-BY-NC-SA) but is a different, earlier hardware revision, not the Plus4 Pro sold today, so it is intentionally NOT listed as a repo for this entry. Parts listed are third-party teardown reports (Kerry Wong / Electro707 blogs, NanoRFE forum) for the V2 Plus4 family generally, not vendor-confirmed for the exact 'Pro' SKU - treat as indicative only.

Specifications

Measurement and model

Exact model: NanoRFE NanoVNA V2 Plus4 Pro
Instrument type: Two-port transmission/reflection VNA; S11 and S21 measurements
Store frequency range: 50 kHz–4 GHz
Detailed specification range: Maker product table lists 50 kHz–4.4 GHz for Plus4/Plus4 Pro
Pro distinction: Adjustable IF bandwidth; maker documents crystal measurement on Pro
Display and body: Touchscreen; store lists 300 g

Power and included tools

USB power: 4.6–5.5 V; maker table lists 500 mA typical without charging
Battery reference: Table lists 3200 mAh for Plus4/Pro; shipment inclusion requires confirmation
Store bundle: SOLT calibration kit and two 30 cm SS405 cables
Antenna connection: SMA measurement port; add the adapter required by the antenna feedline

Setup and build records

Calibration: Calibrate after changing sweep range; use open, short and load at the cable end; thru for transmission
Antenna workflow: Use CH0/S11 with return-loss and SWR traces; adjust the antenna while observing the sweep
Computer workflow: USB connection; NanoVNA-QT provides S-parameter export and calibration options
Useful shared artifact: Maker guide describes exporting measurements and screenshots to document antenna builds

What still needs checking

Store and detailed specification table disagree on the upper frequency limit. Summary uses the store’s 4 GHz figure; confirm exact hardware/firmware before relying on operation beyond it.
Cell inclusion, exact supplied battery, USB connector/cable bundle and shipment timing were not established for the Pro order.
Accuracy, dynamic range and calibration stability were not independently measured. Do not translate matching impedance into a measured communication-range improvement.
This proposal is for the NanoRFE Plus4 Pro, not all products sold under the NanoVNA name. Current Plus4-family hardware is not established here as openly licensed.
Price remains null. Tax, shipping, stock at checkout and rights to republish product media remain unresolved.
