Description

An add-on board which allows placing additional hardware for OnStep on a RAMPS board

README

onstep-ramps-shield

This is an add-on board for a RAMPSv1.4 (and some later versions) board, which carries a bit of additional hardware necessary for an OnStep telescope controller.

There are different ways to build an OnStep, including using a completely custom board, but I liked the modular approach and used an Arduino Mega in combination with a RAMPS shield. The custom boards of course offer places to fit connectors and such which the Arduino/RAMPS combination doesn't, so I'm trying to build this board to help with that.

At the moment, the board takes the following components:

• RA motor connector, RJ12 6p6c
• DEC motor connector, RJ12 6p6c
• Focuser motor 1 connector, RJ12 6p6c
• Focuser motor 2 connector, RJ12 6p6c
• (Polar alignment scope illuminator connector, 3-Pin 3.5mm audio jack)
• (PEC sensor connector, 3-Pin 3.5mm audio jack)
• Buzzer
• DS3231 RTC via I2C
• BME280 environmental sensor via I2C
• HC05 Bluetooth module via Serial
