- For Wi‑Fi 6 with 2.4/5 GHz support: FireBeetle 2 ESP32-C5 IoT Development Board (2.4 / 5GHz Wi-Fi 6, Solar Charging, Home Assistant) (Wi‑Fi 6 2.4/5 GHz) ($16.95)
- For a simple 2.4 GHz Wi‑Fi module option based on ESP8266: WT8266-S1 WiFi Module Based on ESP8266 (2.4 GHz Wi‑Fi) ($13.80)
nRF24L01+ (2.4 GHz) RF transceiver parts
- For the core radio IC: 2.4GHz Transceiver IC - nRF24L01+ (2.4 GHz transceiver) ($8.00)
- For a ready-to-use long-range module: NRF24L01+PA+LNA Wireless Module - 1100 Meters (PA+LNA, long-range) ($6.80)
- For a higher-power 100 mW module: High Power 100mW 2.4G Wireless Transceiver Module RF Communication NRF24L01P+PA (100 mW, 2.4 GHz) ($13.85)
2.4 GHz antennas (choose by connector)
- For U.FL/IPEX devices (adhesive antenna): PCB Antenna - U.FL (2.4GHz) (2.4 GHz, U.FL) ($4.35)
- For dual-band 2.4/5.8 GHz: Dual Band Antenna - U.FL (2.4GHz, 5.8GHz) (2.4/5.8 GHz, U.FL) ($5.05)
- For a higher-gain U.FL/IPEX whip: 2.4GHz 6dBi Antenna with IPEX Connector (6 dBi, IPEX) ($7.55)
- For RP‑SMA gear (routers/modules): 2.4GHz Dipole Swivel Antenna with RP-SMA - 5dBi (5 dBi, RP‑SMA) ($20.25)
- For a directional long-link option: 2.4GHz 14dbi Directional Panel Antenna kit for WiFi Router (14 dBi panel, directional) ($18.90)
If you meant a 2.4 GHz CPU (not wireless)
- For a keyboard-style desktop Pi running at 2.4 GHz: Raspberry Pi 500 (2.4 GHz quad-core, 8 GB RAM) ($329.00)
