The Benduino system is based on the well known Marcduino 1.5 compact. It controls animations (panel movement, lights and sound) of the droid and was developed 2020.
The benefits over the Marcduino compact 1.5 are:
- the firmware is running on a standard Arduino Pro Mini 5V/16MHz (or Nano) -> cheaper and faster than soldering your own Arduino board
- fully compatible with the Marcduino firmware
- all (well most) needed pins are available as terminals
- comes in 3 variations that allow more compact and cheaper pcbs with full function
- As BodyMaster there’s a special Flashfile to adjust servo movement, travel, direction & speed (see Astrocomms)
The Benduino Pro Mini v1.9.2:
The Benduino is a drop in replacement for the existing Marcduino compact.
Same features, can run the same firmware but runs of a Pro Mini/Nano. All needed pins are there and it has it’s own power terminal for the servos.
And it can run the customizable Body firmware attached below.
The Double Benduino v1.3:
The Double Benduino is a drop in replacement for the existing Marcduino compact Dome Master/Slave setup.
Same features, can run the same firmware but runs of 2 Pro Mini/Nano. All needed pins are there and it has it’s own power terminal for the servos.
All the connections between Master/Slave are on the PCB, so less wiring for you.
The Benduino Pro AIO v1.4.3:
The Benduino Pro AIO is the biggest Benduino in the lineup. The pcb has 3 Arduino Pro Minis on board: Master / Slave / Flthy Holosystem
Less wiring, more compact etc. Form factor of 101 x 71mm
It also has 2 voltage regulators included. The small one runs the Arduinos (wich need only less power) and the bigger one powers the servos (supported by capacitors) with 6V and~2.5A.
If you need more power this buck converter can be replaced with the Pololu D24V50F5 which provides 5V and 5A.
There’s even the option to power master and slave servos via an external power in individually.
All needed pins are screw terminals and via the dip switch selector you select if you use the Astrocomms or not.
