Key Features
- Integrated 802.11b/g/n Wi-Fi transceiver covering 2.4 GHz to 2.4835 GHz with PCB trace antenna eliminates external RF components
- Onboard PIC32 MCU core enables standalone firmware execution without a separate host processor for IoT edge applications
- Surface-mount module with pre-certified RF design simplifies regulatory approval for FCC, IC, and CE certification in end products
Applications
The WFI32E01PE is targeted at IoT sensor nodes, industrial wireless data loggers, and smart home appliances that require embedded Wi-Fi connectivity with local processing capability from a single compact module. Its integrated PIC32 MCU allows the host application to run directly on the module, reducing total BOM cost and PCB area compared to discrete MCU plus Wi-Fi chipset solutions.

Frequently Asked Questions
What Wi-Fi standard and frequency band does the WFI32E01PE support?
The WFI32E01PE supports IEEE 802.11b/g/n Wi-Fi in the 2.4 GHz ISM band, spanning 2.4000 GHz to 2.4835 GHz across 13 channels. The 802.11n mode provides up to 72 Mbps physical-layer throughput, while 802.11b backward compatibility ensures interoperability with legacy access points and infrastructure.
Does the WFI32E01PE require a separate host MCU, or can application code run directly on the module?
The WFI32E01PE integrates a PIC32 MIPS-based MCU core directly on the module, allowing application firmware to run without an external host processor. This embedded MCU architecture reduces system BOM by eliminating a separate 32-bit MCU and the SPI or UART bridge that a host-controlled Wi-Fi module would require.
What type of antenna does the WFI32E01PE use, and how does that affect PCB layout?
The module uses a PCB trace antenna that is integrated directly on the module substrate, so no external antenna connector, cable, or chip antenna is required. Designers must follow Microchip's keepout zone guidelines — typically a 5 mm clearance around the antenna trace — to avoid detuning the antenna and degrading TX output power or RX sensitivity below the rated levels.
Is the WFI32E01PE pre-certified for FCC and other regulatory bodies, and what does that mean for product development timelines?
Yes, the WFI32E01PE carries pre-certification for FCC Part 15, IC, and CE, meaning end-product manufacturers can claim modular transmitter certification rather than undertaking full product-level RF testing. This pre-certification can reduce regulatory approval timelines by 8 to 16 weeks and eliminate $10,000 to $30,000 in custom RF compliance testing costs for small-volume IoT product launches.
