Update: We are working on a revision B of Replicape with one of the most important aspects being a lower price, which has been a sticking point for this product. The MRSP goal for the new revision will be $99, and thus we have decided to lower the price of this board to that level for the remaining boards.
Replicape is an open source 3D printer cape for BeagleBone. It’s super fast, easily hackable and it has the Internet. It’s also our first product, and we’re extremely proud of it.

Here are the most important specs:
– 1GHz of raw power (on the BBB)
– 5 stepper motor drivers (DRV8825)
– 3 high power MOSFETs for 2 extruders and 1 HPB
– 3 medium power PWM controlled MOSFETs for up to 3 fans/LED strips
– 3 analog input ports for thermistors. Noise-filtered inputs and option for shielding
– 6 inputs for end stops
– 1 bus for Dallas 1W temperature sensor for monitoring the cold end. Up to 10 sensors can be added to the bus.
– Microstepping individually programmable for each SMD from 1 to 32.
– All steppers are controlled by the Programmable Realtime Unit (PRU) for hard real time operation.
– Single 12 to 24V PSU, fans are still 12V.
– Compatible with BeagleBone and BeagleBone Black
– Controllable via Ethernet, USB and Manga Screen
– Rugged connectors and lots of protection makes it ideal for development.
– Open source software written in Python for maintainability and hackability.
– Both hardware, firmware and software are open source under the CC BY-SA licence
