Buying Guide
Summary

SparkFun Electronics 14740 is evaluated in RF Transmitters category when frequency coverage and integration details must hold up in the real enclosure. Key specs include Description (HX1 VHF NARROW BAND FM APRS TRAN), Package/case (7-SIP Module), Mounting (Through Hole), and Packaging (Bulk).

Selection Notes
  • For 14740, double-check the mounting type (Through Hole) for your intended installation method.
  • Confirm the supply current (140mA) is acceptable for standby and active operation.
  • Confirm the operating frequency (144.39MHz) and any related tolerance requirements.
  • Make sure Data Rate (Max) (3kbps) aligns with your design targets and verification plan.
Alternates & Substitutions
  • For RF Transmitters, treat alternates as an integration task and validate the assumptions that matter on the assembled system.
  • If substitutions are likely, write down the non-negotiables and re-check them when the supply chain changes, not after field failures.
  • For substitutions, match the footprint-related items first: package/case 7-SIP Module, supplier package Module, mounting Through Hole.
  • For RF substitutions, match the operating band and interface, then validate insertion loss and return loss in your real signal path.

Application Scenarios

Selecting SparkFun Electronics 14740 for RF Transmitters usually comes down to meeting the system constraints that matter most: limits, interfaces, and testability in the real build. In practice, their specifications directly influence link budget, sensitivity, selectivity, and emission margins in crowded spectrum environments. In real deployments, good RF building blocks accelerate certification and reduce re-spin risk in antenna-to-baseband designs. Across smart meters, stable RF performance reduces read failures caused by temperature drift and installation variability. In wireless meters, stable front-end behavior across temperature drift prevents read failures in outdoor deployments. Across medical telemetry, RF designs emphasize predictable link margin and controlled emissions around sensitive instruments.

Compatibility Advice
  • Validate matching, shielding, and coexistence inside the final enclosure so range and emissions are measurable before committing to volume builds.
  • Validate matching, grounding, and shielding in the final enclosure because RF performance is layout- and mechanics-dependent with the final enclosure and cabling.
Project Fit
  • Strongest fit when you can validate SparkFun Electronics 14740 for RF Transmitters integration with production-like fixtures, if you have a defined compliance target and can verify spurs and harmonics under real modulation. However, a weaker fit when integrating SparkFun Electronics 14740 for RF Transmitters, compliance margins are tight but spurs and harmonics are not measured under real modulation, because the key behaviors cannot be confirmed on the assembled system.
