1. FCC Rules
1.1. List of FCC rules
The SHARKY module have received Federal Communications Commission (FCC) CFR47
Telecommunications, Part 15 Subpart C “Intentional Radiators” single-modular approval in
accordance with Part 15.212 Modular Transmitter approval.
According to FCC Part 15.212 the single-modular transmitter is a completely self-contained
radiofrequency transmitter device that is typically incorporated into another product, host or
device and complies to all the conditions to be defined as a “single modular transmitter”.
The Midatronics SHARKY Modular Transmitter is also compliant to FCC Part 15.247 insofar
as it is a device using a wide band modulation inside the band 2400-2483.5 MHz with a 6dB
bandwidth greater than 500kHz.
2. Introduction
2.1. Description
This document describes the Sharky modules.
Sharky is a complete family of modules that enables customer to test and integrate the new
STM32WB MCU for rapid prototyping and fast time to market.
Sharky modules are based on STMicroelectronics STM32WB55CE, a dual-core MCUs with
wireless support based on an Arm® Cortex®-M4 core running at 64 MHz (application
processor) plus an Arm® Cortex®-M0+ core at 32 MHz (network processor).
With two totally independent cores, this innovative architecture is optimized for real‑time
execution (radio‑related software processing).
The STM32WB55 Bluetooth 5.0-certified device offers Mesh 1.0 software support, multiple
profiles and flexibility to integrate proprietary BLE stacks.
OpenThread-certified software stack is available. The radio can also run BLE/OpenThread
protocols concurrently. The embedded generic MAC allows the usage of other IEEE
802.15.4 proprietary stacks like ZigBee®, or proprietary protocols, giving even more options
for connecting devices to the Internet of Things (IoT).
The Sharky module is available in four versions:
● Sharky with PCB Antenna
● Sharky with uFL connector
● Sharky Pro with Chip Antenna
● Sharky Pro with no antenna
