Dolphin представляет собой чипсет для беспроводной передачи по UART с псевдослучайной перестройкой рабочей частоты (ППРЧ) в ISM-диапазоне частот 902 МГц – 928 МГц (США). Чипсет Dolphin является предварительно сертифицированным FCC базовым проектом и состоит из РЧ-приёмопередатчика TRF6903 и цифровой интегральной схемы специального назначения DBB03. DBB03 содержит прошивку для чипсета Dolphin в своей программной памяти на базе ROM.
Схема электрическая принципиальная и трассировка чипсета Dolphin прилагаются к данному предварительно сертифицированному FCC базовому проекту, который может быть использован для упрощения процесса разработки системы и более быстрого вывода продукции на рынок.
- Аппаратные особенности:
- решение чипсета на базе РЧ-приёмопередатчика TRF6903 и цифровой интегральной схемы специального назначения DBB03 (с прошивкой в программной памяти на базе ROM);
- Работает с ППРЧ и FSK-манипуляцией в ISM-диапазоне частот 902 МГц – 928 МГц (США);
- Решение с самой быстрой перестройкой рабочей частоты на рынке, что позволяет добиться более быстрого сбора данных и более низкого уровня энергопотребления (время закрытия канала 200 мкс, отсутствие необходимости в калибровке при перестройке рабочей частоты);
- для отладки / программирования чипсета Dolphin с помощью определённого головного протокола интерфейса может быть использовано отладочное программное обеспечение или микроконтроллер системы;
- выходная мощность +7 дБм (маломощная версия) и +23 дБм (высокомощная версия);
- рабочее входное напряжение с диапазоном 2,7 В – 3,6 В;
- скорость передачи данных по РЧ 38,4 кбит/сек;
- 50 каналов для перестройки частоты и несколько таблиц для рабочих частот;
- предварительно сертифицирован FCC по результатам тестирований в L.S. Compliance;
- типовое значение величины зоны покрытия (передачи) 1 миля (в высокомощной версии печатной платы) и 0,2 мили (в маломощной версии печатной платы). Типовое значение максимальной дистанции передачи для высокомощной версии Dolphin составляет 1 милю в зоне прямой видимости вне помещения, однако реальное значение величины зоны покрытия (передачи) сильно зависит от среды распространения сигнала, поэтому в неблагоприятных средах с множеством препятствий и помех величина зоны покрытия может быть значительно меньше;
- чувствительность -101 дБм при скорости передачи данных 38,4 кбит/сек.
- Программные особенности:
- простой аппаратный интерфейс UART для внешнего микроконтроллера системы;
- подтверждение получения пакета / попытки передачи пакета заново для обеспечения надёжной передачи данных;
- маршрутизация пакетов для увеличения зоны покрытия (передачи);
- поддерживает сети «точка-точка» и широковещательные сети;
- иерархическое определение сети: у каждого приёмопередатчика имеется ID приёмопередатчика (уникальный), ID сети и ID системы;
- в одной системе могут работать до 65536 приёмопередатчиков;
- разделение сети: обмениваться данными друг с другом могут только приёмопередатчики с одинаковыми ID системы, ID сети и набором частот;
- до 16 уникальных наборов частот. Каждый набор содержит 50 частот. Приёмопередатчики с разными наборами частот не будут обмениваться данными друг с другом;
- модульная прошивка позволяет легко настраивать систему под пользователя.
- Что входит в данный проект:
- инструкции по применению;
- перечень элементов;
- Gerber-файлы;
- схема электрическая принципиальная;
- вспомогательное программное обеспечение;

The MAX1472 transmitter and MAX1473 receiver reference design (RD) is a self-contained evaluation platform for exercising both products as a remote keyless entry (RKE) demonstrator system. With the use of the MAXQ® USB-to-JTAG board (MAXQJTAG-USB), the MAXQ610 microcontroller on both the transmitter key fob board and the receiver board can be programmed by the end user.
A simple interface is provided on the transmitter (Tx) board, including four independent momentary switches and a user feedback LED. The Tx board includes a built-in printed-circuit board (PCB) antenna and operates off of a single CR2032 coin cell battery. The receiver (Rx) board includes one momentary switch and five LED connections to the microcontroller. An SMA connector is provided for attaching various Rx antennas, allowing the user to test different designs. The receiver is powered from a pair of AAA batteries.
Both the Tx and Rx boards are usable as-is. Gerber files are available for simple cut-and-paste designs of either the radio sections or the full implementation.

Consult the Selector Guide in the MAX2680/MAX2681/MAX2682 data sheet for the various combinations of power gain, input IP3, noise figure, and supply current offered by each device. The IF output matching components are optimized for an IF frequency of 70MHz. All matching components may be changed to match RF frequencies from 400MHz to 2.5GHz and IF frequencies from 10MHz to 500MHz. Consult Tables 2 and 4 in the MAX2680/MAX2681/MAX2682 data sheet for component values appropriate for each device at other RF and IF operating frequencies.

Go-IO is an Industrial-Internet-of-Things (IIoT) reference design designed for rapid prototyping and development of configurable industrial-control systems. Typical end applications include Industry 4.0 driven process automation for building automation for intelligent buildings, smart sensors, reconfigurable industrial control systems, and robotics. All these industrial applications require a high performance, robust, configurable solution, which Go-IO provides using a modular approach. These systems are enabled by highly integrated ICs from Maxim Integrated, delivering new levels of performance while delivering lower power dissipation in tiny footprints.
Go-IO has four different boards. The different configurations provide a varying mix of type of I/O channels and communication interfaces to target different end applications.
Design files, firmware, and software can be found on the Design Resources tab. The boards are also available for purchase.
