Project description
Other things to note about Luna:
1. Runs RepRapFirmware. Feature set is based on Duet 3 Mini 5+, with some changes:
- On-board WiFi and Ethernet
- One dual-port driver
- Five on-board regulators: (1) 5V, 3A + 3.3V, 1A for core components (2) 5V 3A + 3.3V, 1A for expansions such as NeoPixel, EXP1, EXP2, etc. and (3) 12V, 3A for 12V devices
- More input/outputs (IO0 - IO6)
2. Dual processor design: ESP32-S3 + SAM E5 microcontroller. ESP32-S3 is a dual-core, 240 MHZ WiFi + Bluetooth SoC with 8MB flash, 512K SRAM; handles networking, storage (SD card) and interfaces (USB, PanelDue, RepRapDiscount Full Graphic Smart Controller).
SAM E5 is a Cortex-M4F microcontroller running at 120 Mhz, with 512KB flash and 196K SRAM; handles kinematics, stepping, digital/analog IO and other real-time control.
3. Will have open schematics and PCB design, created with KiCad. Firmware will also be open (goes without saying as it is RepRapFirmware).
