Archim 1.0

This is Archim v1.0a. The Archim Rambo 1.0 board is an all in one 3D printer motherboard. It is an original RAMBo style design with the Atmel SAM3X8E  processor (same as Arduino Due) and DRV8825 stepper drivers all on one integrated PCB. Archim is named after the mathematician Archimedes. The RAMBo stands for (R)epRap (A)rduino-compatible (M)other (Bo)ard.

Major Features - 5 x integrated 1/32th microstep motor drivers, 6 total PWM Mosfet outputs, 4 thermistor inputs, pwm motor current control (no tiny knobs to tweak), SMPS supports hostless printing on power supply voltages from 10-24V DC, 3 independent ATC fuse protected power rails, native Full Speed USB protected by an ADUM isolator, high quality connectors. It is supported by the Arduino IDE environment using the third party url board feature for easier firmware development.

Archim is intended to be initially supported by our 32-bit firmware fork Marlin4due. It addition we plan support for g2 firmware, RepRapFirmware, and Repetier Firmware. 

The circuit board will arrive pre-assembled, with all electronic components securely soldered to the PCB, ready for use. In the complete kit, you will receive the endstop switches/wire harnesses of your choice, two thermistor wire harnesses, plug connectors, USB cable, & we throw in gold connectors/headers for use on the motors & possible extra fan. Since Archim has nearly all the same connectors as RAMBo, the kit reuses the same components which are listed below.

Archim/RAMBo Complete Kit Includes:

(1) Pre-Assembled Archim PCB
(2) Crimped/housed thermistor wire harness, 914.4mm (36")  *thermistor not included*
(1) 6-pin pluggable terminal block (black)
(5) 2-pin pluggable terminal block (black)
(1) 1x2 positive latch housing & matching gold connectors
(6) 1x4 positive latch housings & matching gold connectors for crimping motor cables
(1) USB Cable, 1.828m (6')
(3) Choice of endstop switch (Mechanical, Optical Assembled (additional charge), Optical DIY Kit)
(1) Matching endstop harness set (Mechanical, Optical), pre-crimped/housed, 609.6mm (24")

Firmware / Hardware Information -
Recommended Power supply 12V-24V DC, 16A+.

Windows 10, Linux and Mac use CDC interface and have hardware driver built in.
Windows legacy hardware driver:

A preconfigured Marlin4due Firmware is preloaded onto the board. Source code for this firmware is here.

To recompile firmware, you will need to select Archim from the Tools -> Board selection menu. To add the Archim board the Board Manager use the Arduino "File -> Preferences" menu and add this url: Archim can then be installed from the Tools -> Board -> Board Manager.
