comment on+reason why i am selling:
this is arduino FIRST ARM board,
it is very powerful, the problem is
NOT ARDUINO, but device suppliers
that provide devices+firmware to
be used is limited and the supported
software need constant updates;
but if you are using those devices
supported on mega2560, i know i did
not have problems, so you should also
not have problems;
and if you use a USB HOST SHIELD 2.0(
and i have ), you can access usb hard drive
upto 2TB

remember this is a board that will take
MAX 3.3v FOR INPUT, and MAX 5V FOR OUTPUT…
so any devices REQUIRES over 5v…you will NEED
A DRIVER, and NOT those arduino sensor shields
because they are all based on 5V…

ALSO this DUE R3 will NOT WORK WITH THESE
ULTRASONIC SENSORS: HC-SR04 OR US-015
AND IT WILL WORK WITH SRF-02(AN ULTRA-SONIC SENSOR
WITH POOR RANGE CAPABILITIES) and us-100

specs:
54 digital input/output pins (of which 15 can be used as PWM outputs),
16 analog inputs,
4 UARTs (hardware serial ports),
16 MHz crystal oscillator

Microcontroller     ATmega2560
Operating Voltage     5V
Input Voltage (recommended)     7-12V
Input Voltage (limit)     6-20V
Digital I/O Pins     54 (of which 15 provide PWM output)
Analog Input Pins     16
DC Current per I/O Pin     20 mA
DC Current for 3.3V Pin     50 mA
Flash Memory     256 KB of which 8 KB used by bootloader
SRAM     8 KB
EEPROM     4 KB
Clock Speed     16 MHz
LED_BUILTIN     13
Length     101.52 mm
Width     53.3 mm
Weight     37 g

CLONE(no clone/compatible by me):
Elegoo MEGA 2560 R3 Board ATmega2560 21$
WITH CABLE

reason for selling: these are my remaining extras from my project
my price: 25$unit price is firm

motor/servo drivers:

arduino vnh2sp30 servo driver 25$
comes with heat sink installed,

i have 8 units, and using 4 to
drive 8 super500 servos each
servo needs CONSISTENT 14amps
and 16VOLTS and this vnh2sp30
monster driver do this

as to battery… you will need battery
that WILL PROVIDE CONSISTENT
MINIMUM 14AMPS+16VOLTS…

vnh2sp30
you will require to use this kind of drive
if your servo/dc motor/stepper requires 12V
and more, otherwise you will not need this driver
SPECS:
Voltage Max: 16V.
Maximum current rating: 30 A.
Practical Continuous Current: 14 A.
Current sensing available to Arduino analog pin.
MOSFET on-resistance: 19 mOhms (per leg)
Maximum PWM frequency: 20 kHz.
Thermal Shutdown.
i have 4 units left
servo that needs CONSISTENT
14amps and 16VOLTS and this
vnh2sp30 monster driver do this

as to battery… you will need battery
that WILL PROVIDE CONSISTENT
MINIMUM 14AMPS+16VOLTS…

for reference+program code on how to use this vnh2sp30:
https://www.instructables.com/id/Monster-Motor-Shield-VNH2SP30/
and you will need to download and use arduino ide to do the programming

comment on:
a) vnh2sp30 aka monster driver, it is very powerful
and if you do not have any servo/stepper that needs
CONSISTENT 14v AND 14A, you will not need this driver

b) vnh3sp30 … it is MUCH MORE COMPACT+
FUNCTIONAL, as i have, you will have
a problem to connect to an arduino/
raspberry pi because of the pins

battery holder 6 cells 1.5v AA with jack
9 units available, my price: 5$/unit FIRM

reason for this sale: i found a jack
to hook 6 pcbs into 2 of these battery holders

prices by popular sites
amazon.ca 21.99 for 2 units+shipping+tax
there cheaper ones, like 3.77$cd…without the jack
