introructionIntroductionARM Cortex -M3 and Cortex -M4 are increasingly popularmicrocontrollers. They are rich with modules, with high performanceand low power consumption, so creating a development board thesize of EasyMx PRO v7 was really a challenge. We wanted to put asmany peripherals on the board as possible, to cover many internalmodules. We have gone through a process of fine tuning theboard's performance, and used 4-layer PCB to achieve maximumefficiency. Finally, it had met all of our expectations, and evenexceeded in some. We present you the board which is powerful,well organized, with on-board programmer and debugger andis ready to be your strong ally in development.EasyMx PRO v7 development TeamTwo connectors for each portReady for all kinds of developmentAmazing connectivityEverything is already here mikroProg on boardMultimedia peripheralsmikroBUS supportEasyMx PRO v7 is all aboutconnectivity.

power supplyPower supplyBoard contains switching power supplythat creates stable voltage andcurrent levels necessary forpowering each part of the board.Power supply section containsspecialized MC33269DT3.3power regulator which createsVCC-3.3V power supply, thus makingthe board capable of supporting 3.3Vmicrocontrollers. Power supply unit can be poweredin two different ways: with USB power supply, and usingexternal adapters via adapter connector (CN16) or additionalscrew terminals (CN15). External adapter voltage levels must be inrange of 9-32V DC and 7-23V AC. Use jumper J1 to specify which powersource you are using. Upon providing the power using either external adapter, orUSB power source, you can turn the board on using SWITCH 1 (Figure 3-1).Figure 3-1: Power supply unit of EasyMx PRO v73.3V VOLTAGE MPRMC34063A5V SWITCHING POWER SUPPLY87R660.2265VCC-EXTD1D2CN16 1N40071N4007 RR592K21N4007R711KFigure 3-2: Power supply unit schematicspage 6EasyMx PROv7

supported MCUsDefault MCU cardMicrocontrollers are supported using specialized MCU cards containing 104 pins,which are placed into the on-board female MCU socket. There are several types ofcards which cover all microcontroller families of Stellaris Cortex -M3, as well asCortex -M4. The Default MCU card that comes with the EasyMx PRO v7 packageis shown on Figure 4-1. It contains LM3S9B95 microcontroller which is loaded withon-chip modules and is a great choice for both beginners and professionals. Aftertesting and building the final program, this card can also be taken out of the boardsocket and used in your final device.1LM3S9B95 is the default chip of EasyMx PRO v7. It belongs to ARM Cortex M3 family. It has 80MHz operation, 256K bytes of linear program memory, 96Kbytes of linear data memory. It has integrated Ethernet controller with PHY,USB (OTG, Host, Device), up to 65 General purpose I/O pins, five 16-bit timers,16 Analog Input pins (AD), three UARTs, internal Real time clock (RTC), a pairof each: I2C, SPI and CAN controllers. It also contains 3 analog comparators,16 digital comparators. It is preloaded with StellarisWare libraries andbootloader in ROM.28MHz crystal oscillator. We carefully chose the most convenient crystalvalue that provides clock frequency which can be used directly, or with the PLLmultipliers and dividers to create higher MCU clock value.325MHz crystal oscillator. This crystal oscillator is connected to internalEthernet module.4VREF jumper. This jumper determines whether PB6 pin is used as voltagereference for A/D converter, or it is used as general purpose I/O pin. Jumper issoldered to VREF position by default.2134Please note that if VREF jumper is resoldered to I/O position Touch Panelcontroller will not operate correctly, because it uses voltage from this pin asa reference for A/D conversion.Figure 4-1: Default MCU card with LM3S9B95page 8EasyMx PROv7

supported MCUsHow to properly place your MCU card into the socket?Before you plug the microcontroller card intothe socket, make sure that the power supply isturned off. Images below show how to correctlyplug the card. First make sure that MCU cardorientation matches the silkscreen outline on the1Figure 4-3: On-boardMCU socket has silksreenmarkings which will helpyou to correctly orient theMCU card before inserting.page 10EasyMx PRO v7 board MCU socket. Place the MCUcard over the socket, so each male header enclosesthe right angle with the female socket, as shownin Figure 4-4. Then put the MCU card slowly downuntil all the pins match the socket. Check again if2Figure 4-4:Place theMCU card onthe socketso the pinsare alignedcorrectly.everything is placed correctly and press the MCUcard until it is completely plugged into the socketas shown in Figure 4-5. If done correctly, all pinsshould be fully inserted. Only now you can turn onthe power supply.3Figure 4-5 Properlyplaced MCU card will haveequally leveled pins.EasyMx PROv7
