It combines the Infineon CYW43439 chipset with single-band 2.4 GHz Wi-Fi 4 (802.11n) and Bluetooth 5.2 Classic + LE, using a SISO architecture with integrated PA, LNA and a shared 2.4 GHz antenna.Using a pre-certified radio module helps reduce RF design complexity and the number of external components needed for wireless connectivity. It is suited to OEM and embedded designs where Wi-Fi and Bluetooth need to be added without starting the radio design from scratch.The module uses a low-pin-count gSPI host interface and provides three host-controlled GPIOs for extra I/O flexibility. It is supplied in a 21-pad castellated package for mounting to your own board and is compatible with the Raspberry Pi Pico SDK.Features:Chipset: Infineon CYW43439 Wi-Fi + Bluetooth combo chipsetWi-Fi: Wi-Fi 4 (802.11n), 2.4 GHz band only, up to 96 Mbps PHY data rateBluetooth: Bluetooth 5.2 (Classic + BLE), ~100 m range (Class 1), ~10 m range (Class 2)RF integration: Integrated PA, LNA, and shared 2.4 GHz antennaHost interface: low-pin-count gSPIAdditional I/O: 3 host-controlled GPIOsSoftware compatibility: Raspberry Pi Pico SDKCertification: Full modular certifications (radio/regulatory)Production lifetime: Guaranteed production until at least January 2036Specifications:Chipset: Infineon CYW43439 Wi-Fi + Bluetooth combo chipsetWi-Fi: Wi-Fi 4 (802.11n), 2.4 GHz band only, up to 96 Mbps PHY data rateBluetooth: Bluetooth 5.2 (Classic + BLE), ~100 m range (Class 1), ~10 m range (Class 2)RF integration: Integrated PA, LNA, and shared 2.4 GHz antennaHost interface: low-pin-count gSPIAdditional I/O: 3 host-controlled GPIOsPower consumption: Idle (PM1, DTIM1): ~1.19 mAReceive at –50 dBm: ~43 mATransmit at 16 dBm: ~271 mAOperating voltage: supplied via host (typical 3.3 V I/O domain)Operating temperature range: –30 °C to +70 °CPackage: 21-pad castellated moduleDimensions: 16.5 mm × 14.5 mm × ~2.55 mmSoftware compatibility: Raspberry Pi Pico SDKCertifications: Full modular certifications (radio/regulatory)Guaranteed production: until at least January 2036A practical module for product designers adding Raspberry Pi Pico SDK-compatible Wi-Fi and Bluetooth connectivity to embedded hardware. **Product Type:** Wireless Module ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDQ8ECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--836e3d9dff4858ebc9498c839fd632bbbe8f24a6/29424-RPi-Radio-Module-RMC20452T-Feature.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDRsECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--b2ff79653b785fde9e633df74c2a6d2257c9405a/29424-RPi-Radio-Module-RMC20452T-Front.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDR8ECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--4fd11b52a02f9df1c7c26867b369c62e9e89d250/29424-RPi-Radio-Module-RMC20452T-Back.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDScECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--0ca1b994d03cff8251a7384e212ad9098459bb24/29424-RPi-Radio-Module-RMC20452T-Scale.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
