![]() Note: You will need a USB to Serial Converter to program the Arduino Pro Mini The latest and greatest version of this board breaks out the ADC6 and ADC7 pins as well as adds footprints for optional I2C pull-up resistors! If you’re supplying unregulated power to the board, be sure to connect to the “RAW” pin and not VCC. There is a voltage regulator on board so it can accept voltage up to 12VDC. The Arduino Pro Mini also works with the FTDI cable but the FTDI cable does not bring out the DTR pin so the auto-reset feature will not work. This board connects directly to the FTDI Basic Breakout board and supports auto-reset. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers. LM 2596-5 voltage variation will be between (4.8 to 5.The Pro Mini 328-5V 16MHz based on Arduino®i is a microcontroller board based on the ATmega328 ( datasheet). LM-2596-5 Buck converter I am using is correct or some better alternative is available.Īs suggested by Paul_B, What's would be the benefit of routing separate optocoupler input and output ground as ultimately the chassis and battery ground is same.Īs suggested by wolframore :- Kindly suggest some protection circuitry that I can add to increase system robustness and reliability But what would be the benefit of it as the chassis ground and battery ground will be same (After Euro-4 all the chassis is connected with battery ground). :- I did not exactly get your ground part kindly confirm if my understanding is correct :- You mean that i should separately route the optocoupler input ground and Optocoupler output ground. :- I will be using PIC847 (4 packs opto coupler), Optocoupler will be mounted on the same PCB as that of Arduino board #12 Paul_B :- I will be using LM-2596-5 buck converter #11 railroader :- it's a diesel truck, with two 12V battery. :- I will definitely remove the 10K pull up resistor. #10 wvmarle :- you mean ,as I am using optocoupler the protection against negative transients won't be required (am i right in understanding your point?) ![]() #9 Wolframore :- Exactly I want my design to be fool proof, Kindly suggest to improve it's reliability Yes my system will be connected and is expected to work while starter motor is engage and starting the truck engine. Truck is Diesel truck hence while starting the truck, We observe a drop of potential of around 1 V DC hence on safer side I have mentioned 22 V DC. It shows that when the battery is charged potential will be 12.6 VDC i.e (2 x 12.6 :- 25.2 V DC ) across battery terminal and while charging or during high throttle it can go up-to 14.7 V DC(29.4 VDC). #8 Paul_KD7HB :- Paul the Truck will be having the standard 2x 12VDC (24VDC) battery only. #7 Wolframore :- The Output won't be indeterminate i feel as when Opto is off, Arduino will get ~+5V (Logic 1)(Due to internal pull up high resistor) and when opto is on arduino will get ~ 0(Logic 0) Optocoupler will be mounted on the same PCB. #4 aarg :- I will omit the 10K pull up resistor and use the internal pull up resistor of arduino But definitely using PLC is too costly therefore I am not thinking of going for that. In my case reliability and robustness of the system is more important then cost. What Additional hardware I can fit in my PCB to increase the reliability of my system.Is Using the Arduino with Buck converter for industrial application is good (Temperature Range :-10 deg C to 50deg C).Using Voltage divider for converting 24VDC to 5VDC is it reliable and best option. ![]() Because of which we will be making the PCB(From PCB Way/JLPCB) and in that PCB will will be mounting Buck Converter, Voltage divider Resistance.īecause we will be using this project for industrial application I am having following questions :. And I am thinking of using voltage divider for converting 24VDC to 5VDC using (38K ohm and 10K ohm resistance).Īnd we will be making 50 units of this. ![]() I am powering my Arduino using 24V DC-5VDC Buck converter. I am making Project For Industrial Application. ![]()
