USA32 Development Board

DevKitC-1 footprint, Wi-Fi 6.
No PRC-headquartered parts.

A development board that fits where an ESP32-S3-DevKitC-1 goes, built around the u-blox IRIS-W106 with no parts from PRC-headquartered makers. Same width and header positions, so a carrier board can stay as it is.

Defense-Aligned Supply Chain

  • No parts from PRC-headquartered makers
  • US or allied fab and per-lot origin set at order
  • FCC and IC modular-approved radio (XPYIRISW1, 8595A-IRISW1)

Defense-aligned describes design and part selection. It is not a certification or a claim of NDAA, TAA or DFARS compliance, or of MIL-STD qualification. Some parts from approved makers may be manufactured in PRC plants. Compliance depends on the fabricator, assembler and part lots for each order and on the requirements in your contract, and we will work through them with you when quoting.

Certified radio module

  • u-blox IRIS-W106 (NXP RW612), internal antenna
  • FCC ID XPYIRISW1, IC 8595A-IRISW1 modular approval

Drop-in carrier fit

  • Power, reset, UART0, BOOT and RGB LED on the same pins
  • 22.86 mm header spacing, as on the S3 DevKitC-1

USB

  • Two USB-C ports replace micro-USB
  • Port 1: Silicon Labs CP2102N USB-UART bridge
  • Port 2: native USB 2.0 High-Speed

Development

  • BOOT and RST buttons with auto-program
  • ROM ISP boot over UART or USB with blhost
  • Zephyr and MCUXpresso support on the RW612

Defense-aligned sourcing

  • No parts from PRC-headquartered makers
  • US or allied fab and per-lot origin set at order

Build

  • Four-layer board with controlled-impedance USB
  • USB-C ports at the same end as the S3 DevKitC-1
