Section 1 Introduction

Description Disclaimer

This kit was designed to enable you to quickly start working with the AT86RF211 TRX01 transceiver and its companion microcontroller AT90 series .

It includes - An embedded demonstration software.
- A PC software and dongle for RF evaluation.
- All the tools needed to build your own stand-alone application development of prototypes batteries, LCD for debugging purposes, In System Programming, 3-bit encoder, push button, connector for external power supply adapter, etc... Software functions required to set up the transceiver and send/receive data are also provided to make it easy to write your own application software. You are welcome to reuse them when it comes to writing your own application software.
- This kit must be regarded as a tool, not a finished product. It allows you to evaluate the performances of the AT86RF211 thanks to relevant measurement devices oscilloscope, spectrum analyzer, etc... , design prototypes by adding sensors or any component required by a given application and debug software. It CANNOT be resold as a finished product that must be compliant with local relevant regulations.
- Since this Development Kit is intended to be used on an industrial workbench and modified by the user to build his prototypes, NO WARRANTY OF ANY KIND can apply. The user MUST read the user guide BEFORE using this kit, to know its features and use it accordingly. NO LIABILITY will be accepted by Atmel, whatsoever may arise as a result of the use of these boards.

Hardware Description

Power Supply

You can work with 1 or 2 batteries AA or AAA as well as an external power supply
connector J1 .

Warning
5V max.
- Plugging a jack connector automatically disconnects the batteries. Note The AT86RF211 dongle requires a 5V power supply to work properly, as well as
some AVR ISP dongles available on the market.
- NO brown-out circuit is mounted on the board, since it depends on the user’s choice of power supply voltage. Mounting such a circuit is very easy since a metallized hole connected to the RESET is available close to Vcc and GND on the board below the “ISP” inscription .

Motherboard

The main features are:
- An LCD for debugging purposes with its own step-up DC/DC converter U2 5V output and level translator U3 . Since a DC/DC converter is a source of noise, its input is filtered by a stage two low ESR tantalum capacitors and a resistor . This resistor may have to be adapted or replaced by an inductance if higher currents are to be delivered.

Note:

This 5V output is available for other circuits. If the AT86RF211 is powered through this 5V converter, output noise could decrease the performances of the transceiver, and an additional relevant filtering stage would have to be added.
- 3 LEDs for debugging purposes DL1 green and DL3 red are connected to microcontroller ports. DL2 yellow is ON when the AT86RF211 is in reception or transmit mode, thanks to comparator U7 useful for debugging Wake-Up mode protocols .
- A 2.5V Voltage Reference for the A/D converter or any other application.
- 2 buttons for Hardware Reset S3 or external interrupt S4 .
- A 3-bit encoder wheel for the selection of any parameter you want.
- GR1 to GR3 to manage the DATACLK signal as an External Interrupt, a Time Input Capture or a standard Input Port depending on your needs. Demo software uses the External Interrupt input pin.
- GR4 to allow Wake-Up from AT86RF211 or External Wake-up wired OR .
- U1 and the components around it are unused, so the user can take advantage of these footprints to place his own AOP and SMD components also 3 footprints of SMD packages on the other side .
- A light sensor RV3.

Hardware Description
- A connector for In System Programming JP2. An Atmel dongle must be used, and its cable simply plugged into JP2. 5V is required by some dongles to work properly.

Several filtering stages are foreseen at critical places radio/digital interface, connectors to the “external world”. Some of them are not used on this evaluation board, but can be implemented if your application requires them without having to cut any trace. On the other hand, once the application is meeting all your specifications, it is naturally possible to cut costs by removing some of these components, such as decoupling capacitors experience shows that it is better to do so in a second step, once everything works .
