Raspberry Pi 4 (2GB RAM)

The Raspberry Pi 4 Model B (2GB) is a powerful upgrade for ham radio and RF projects, offering significant performance improvements over previous models. With a quad-core Cortex-A72 SoC, USB 3.0, Gigabit Ethernet, and dual micro-HDMI outputs, it’s ideal for SDR servers, hotspots, station automation, and digital mode gateways.

Specifications
  • Processor: Broadcom BCM2711, quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.8 GHz
  • Memory: 2 GB LPDDR4-3200 SDRAM
  • Networking: Gigabit Ethernet, 2.4/5 GHz 802.11ac Wi-Fi, Bluetooth 5.0, BLE
  • USB: 2 × USB 3.0, 2 × USB 2.0
  • Display: 2 × micro-HDMI (up to 4Kp60)
  • Multimedia: H.265 4Kp60 decode, H.264 1080p60 decode, 1080p30 encode
  • Expansion: 40-pin GPIO header (backwards compatible)
  • Other I/O: Stereo audio/composite video, MIPI DSI, MIPI CSI
  • Storage: microSD slot
  • Power: 5 V via USB-C (min. 3A) or GPIO header
  • PoE: Supported via PoE HAT (sold separately)
  • Operating temp: 0 – 50 °C ambient

What’s Included

  • Raspberry Pi 4 Model B with 2GB RAM
  • Standard 40-pin GPIO header (pre-soldered)

Great For

  • Running SDR applications such as remote HF receivers
  • Digital hotspots (D-Star, DMR, Fusion, MMDVM)
  • Station automation and logging servers
  • Networked APRS/iGate nodes and packet systems
Power Options for Raspberry Pi 4
  • Powerpole HAT for Raspberry Pi 4 — feeds Pi 3/4/5 directly from 13.8 V shack power, rated for 3A+ continuous.
  • Prefer clean shack integration? Use Powerpole DC feeds instead of noisy wall-warts for reduced RF noise in SDR and hotspot setups.

Tip: The Pi 4 can draw >3A with USB devices attached — size your supply and cabling accordingly.

Mini-FAQ: Raspberry Pi 4 (2GB) for Ham Radio

  • Is 2GB enough for SDR? — Yes, for single-channel SDR (HF receivers, hotspots, WSJT-X). For multi-channel or heavy GUI work, 4–8GB is recommended.
  • How do I power the Pi 4 from my 13.8V shack supply? — Use our Raspberry Pi Powerpole HAT, designed for direct integration with shack power.
  • Can I run a hotspot on the Pi 4? — Absolutely. The Pi 4 provides enough headroom for DMR/D-Star/Fusion hotspots, with room for logging or iGate tasks in parallel.
  • Does the Pi 4 produce RF noise? — Like all SBCs, it can. Keep power clean, choke USB leads, and use shielded enclosures where possible for sensitive RF setups.
