STMicroelectronics 收发器开发套件 &子板

STMicroelectronics 收发器开发套件 & 子板基于 SPIRIT1——一个 sub-GHz、低功耗、低数据率收发器，适用于 ISM 频带及无线 M-BUS。这三款开发套件在三个不同频带（169MHz、433MHz 和 915MHz）可用。每个母板有一个 USB 连接器（用于 PC GUI 接口）以及 JTAG 连接器（用于在 MCU 上开发固件）。子板配备外部平衡-非平衡转换器，优化了尺寸、RF 性能并减少了外部 RF 元件的数量。

Development Kits

STMicroelectronics Transceiver Development Kits include two RF Daughterboards based on the SPIRIT1 low-power, sub-GHz low data rate transceiver suitable for ISM bands and wireless M-BUS, and two motherboards based on the STM32L low-power microcontroller to control the daughterboards. Each motherboard features a USB connector for PC GUI interaction and firmware updates. A JTAG connector allows the development of specific firmware on the microcontroller.

Daughterboard

STMicroelectronics STEVAL-IKR002V4B Transceiver Evaluation Daughterboard is based on the SPIRIT1, a sub-GHz low-power, low data rate transceiver suitable for ISM bands and wireless M-BUS. This board is equipped with external balun, matching, and filter in a single BALF-SPI-01D3 device that optimizes size, RF performances, and number of external RF components (from 16 SMD passive components to just one).
