Product details
Overview
STEVAL-SP1ML868 from STMicroelectronics is a USB evaluation dongle for the SP1ML-868 868 MHz low-power sub-GHz RF module, integrating SPIRIT1 transceiver IC, on-board PCB antenna, USB-powered operation (4.5–5.5 V), and AT-command firmware interface for rapid RF link prototyping in industrial sensor networks.
For engineers reviewing the STEVAL-SP1ML868 datasheet, STEVAL-SP1ML868 pinout, STEVAL-SP1ML868 application, or STEVAL-SP1ML868 equivalent, this tool enables immediate host-PC-based RF evaluation without custom hardware-supporting quick validation of range, packet error rate, and command-driven configuration in LPWAN edge nodes.
Technical Context
The dongle implements a USB-to-SPIRIT1 bridge using CP2102 USB-UART converter and SP1ML-868 RF module, with firmware exposing UART-based AT commands to configure modulation (2-FSK/GFSK), data rate (up to 500 kbps), output power (−10 to +13 dBm), and packet handling (CRC, whitening, auto-ack).
It provides direct access to SPIRIT1 I/O signals-including WKUP (wake-up/shutdown control), GPIO0/GPIO1 (user-programmable digital I/O), MODE0/MODE1 (operating mode selection), and SWDIO/SWCLK (firmware reprogramming)-via exposed test pads, enabling hardware-level integration testing beyond AT command abstraction.

FAQ
Is STEVAL-SP1ML868 FCC/CE certified for end-product use?
No. The STEVAL-SP1ML868 is an unqualified evaluation tool intended solely for lab-based RF characterization and firmware development. It lacks full regulatory certification (FCC ID, CE RED) and must not be deployed in commercial products without redesign and independent compliance testing.
Can the onboard SP1ML-868 module be replaced with SP1ML-915?
No. STEVAL-SP1ML868 is hardware-specific to the SP1ML-868 module (868 MHz); the SP1ML-915 variant (915 MHz) requires different RF matching components and is supported only on the separate STEVAL-SP1ML915 board.
What firmware version ships with STEVAL-SP1ML868?
The board ships with preloaded AT-command firmware (v1.x, DocID027158 Rev 1), supporting basic RF configuration, packet transmission/reception, and GPIO control. Firmware updates require SWD programming via the SWDIO/SWCLK pads and ST-LINK/V2.
Does the dongle support over-the-air (OTA) firmware updates?
No. OTA updates are not implemented. Firmware revision requires physical connection to the SWDIO/SWCLK test pads using an ST-LINK debugger and STM32CubeProgrammer; no UART-based bootloader or wireless update capability is provided.
