The STEVAL-SP1ML868 and STEVAL-SP1ML915 boards are design tools that allow evaluation of ST's SP1ML-868 and SP1ML-915 low power RF modules in a quick and simple way.
The dongle includes the module to evaluate, an on-board RF antenna, and a USB connector. The USB connector is used to connect the dongle to a PC, to access the sub GHz RF module and to supply the dongle.
The STEVAL-SP1ML868 and STEVAL-SP1ML915 downloaded firmware enables the user to create a SPIRIT1 link using simple AT commands.
The SP1ML-based dongle is not qualified. It is a demonstration tool only, to be used strictly for evaluation purposes. It is not a product in itself.
The STEVAL-ISA180V1 evaluation board implements a wide mains range flyback isolated converter (12 V - 0.6 A), developed for general purpose applications.
This high-voltage converter intelligently integrates an 800 V rugged power MOSFET with PWM current-mode control. The core of the application is the new VIPer0P off-line high voltage converter from VIPerPlus family with zero power features.
The evaluation board features a small size and minimal BOM, high efficiency, low standby consumption and high reliability due to these protections: pulse skip mode to avoid flux-runaway, delayed overload protection (OLP), max duty cycle counter, VCC clamp and thermal shutdown.
