Modules & Development Kits
Single band Wi-Fi (QCA4010) and Bluetooth Low Energy (CSR8811)

RB01 (baseboard) / RB04 (module) design
The RB04 module, based on QCA4010 and CSR8811, is a single band 1x1802.11b/g/n and BLE v4.1 capable device optimized for embedded applications requiring Wi-Fi and Bluetooth Low Energy (BLE) v4.1 connectivity. QCA4010 chipset within RB04 is an integrated network processor with a large set of TCP/IP with IPv4/IPv6-based services and CSR8811 is a single-chip BLE radio and baseband IC.
RB04 module includes the following components:
- QCA4010 chipset
- CSR8811 chipset
- PCB / printed antenna shared between Wi-Fi and BLE
- An integrated Balun designed to help save cost and size, minimize tuning and tolerance
- Footprint for Apple MFI
- 2MB SPI Flash memory
RB04 module can be either used with RB01 development kit for software development or incorporated into OEM products to enable rapid deployment of Wi-Fi connected systems.
Please check Documentation – Hardware section for more details about RB04 module and associated kit.

RB01 (baseboard) / RB02 (module) design
The RB02 Wi-Fi module, based on QCA4010, is a single band 1x1
802.11b/g/n device optimized for low-power embedded applications with single-stream capability for both Tx and Rx. It has an integrated network processor with a large set of TCP/IP with IPv4/IPv6-based services.
RB02 module includes the following components:
- QCA4010 chip
- An integrated Balun to save cost and size, minimize tuning and tolerance
- PCB / printed antenna
- Footprint for Apple MFI
- 2MB SPI Flash memory and etc.
