A 3D printer control board based on ESP32This is a 3D printer control board based on the ESP32 microcontroller, which comes with built-in WiFi and BlueTooth.Current version: v0.5rev1 AUX1 adapter Fixes issue with AUX1 port on MRR ESPE v0.5This adapter board fixes MRR ESPE v0.5's issue with the TX/RX pins being swapped on the AUX1 connector. Simply use an IDC cable to connect AUX1_BRD to the AUX1 connector on the board. Then connect AUX1_SCRN to the screen (such as MKS TFT32). EXP3 to EXP1/2 adapterAdapter to allow use of RepRap full graphics smart controller This adapter allows the MRR ESPE to use generic LCD12864 controllers (officially the RepRap full graphics smart controller). To do so, connect EXP3_BRD to the LCD connector on the MRR ESPE. Then, connect EXP1 and EXP2 on the adapter to EXP1 and EXP2 on the controller. (Optional: Connect D5, D6, D7 to unused native ESP32 pins on the MRR ESPE, like IO2, IO4, and IO15. Then define `LCD_PINS_D5`, `LCD_PINS_D6`, and `LCD_PINS_D7` in `pins_MRR_ESPE.h`. The KILL pin is also optional.) If you want to use the SD card on the controller: 1. Remove SD_EN jumper on the MRR ESPE board.2. Use jumper wires to connect SCK, MISO, and MOSI from the adapter to the respective pins on the board.3. Connect SS on the adapter to IO5 on the board.4. Optional: Connect DET to an unused pin on the board. You will need to edit `pins_MRR_ESPE.h` to define the `SD_DETECT_PIN`.

Is a 3D printer controller that aims to provide a full stack user experience around Octoprint / Marlin using a custom designed board that integrates a Raspberry Pi 3 or Zero W. It will also provide a solid, powerfull hardware by utilizing quality components, a STM32 32bit MCU and powerfull TMC5160 or TMC2160 driver (SD / SPI mode).Features32bit STM32H743VI 400Mhz / 1024KiB RAM / 2MiB Flash MCU / 4 KiB EEPROMIntegrated Raspberry Pi 3 / Zero W HAT connector as the main user interfaceIntegrated DC/DC switching module for 5V / 3.3V power supply5x TMC5160 or TMC2160 stepper driver with 8x external Power MOSFET each3x high power MOSFET for heating (2x heater, 1x heatbed, 24V)4x low power MOSFET for fans (5V or 24V)40 pin external connector for STM32 and Pi GPIO pinsGPIOPWMUARTSPII2C3.3V / 5V / GND for external power consumptionMicro SD Card for storing GCODE files (directa MCU access)Designed for a 24V power supplyAutomotive fusesQuality connectorsOctoprint plugin for flashing the firmware of the board (STM32)Stepper driverYou can use both TMC5160 or TMC2160 as the stepper driver, since they both are functionally / pin equal when used in SD / SPI-Mode.It doesn't mater choosing one over the other, other than price and availability.Fine tuning of the MOSFET driver may be necessary.

This is my dock\new project: it's a small dock (same size as the mini dock and the omega) for the Onion Omega 2 and 2+.I needed the smallest dock i could do, that featured:EthernetType A USB hostMicro USB for powerIt has an onboard linear voltage regulation (i didn't bother going with a switching one for such low power), magnetics integrated in the RJ45 connector to save space, USB host ESD protection (diode array), USB host PTC fuse.On the left side there is the RJ45 connector and nothing on the back side of the board, so that you can easily access the MicroSD card on the Omega 2+. On the right side (the antenna side of the omega) you have the USB type A connector, facing outwards, and the microusb connector for power, facing inwards.The first version, v0.9, had some issues with the ethernet. Currently i've released v1.0 that solves all the issues, adds a led to check power and, making a better use of the space, the RJ45 connector doesn't protrude anymore. I haven't ordered the v1.0 PCBs yet, but the circuit is tested.I've chosen 0805 passives, 1206 ptc fuse, big smd electrolitic caps, a SOT223 (the classic 1117) for power regulation and a SOT23-6 for usb host protection, so it can all be easily handsoldered with just a plain soldering iron. Probably the hardest part to handsolder is the SOT23-6 but it's easily doable by hand.

[ESP-Helios] is a 3D printed motherboard based on esp32 .It uses marlin firmware, detailed information can be accessed https://marlinfw.org/ understand . 1. The ESP-Helios printer control board has five drivers, two of which are used for dual-z control.2. ESP-Helios can choose different drivers according to their needs.3. Only one OLED screen interface (ICC interface) and one encoder interface are reserved on the motherboard, and you can set the pin definition to use the serial screen.4. Comes with 3 high-power mos. The hot bed can be driven directly. (If the current required by the hot bed is too large, it is recommended to connect a larger MOS).5. 5. The size of ESP-Helios PCB is only 80 * 80, but 5 drive shafts are plugged on such a small motherboard.https://marlinfw.org/%E4%BA%86%E8%A7%A3

Stepper motor drive board. This design is a stepper motor open-loop driver board, using STC15W408AS microcontroller as the main control, 12V power input, using two A4950 motor drives, the maximum current can reach 3.5A. The three inputs are isolated by optocoupler, even if the driver board is blown up, the main control will not be blown. The four DIP switches can adjust the subdivision and current (torque). The serial port interface is reserved for burning programs or for monitoring and debugging.The DIP switch is used to adjust the subdivision and current.Subdivision [1: 2] = 00: no subdivision, = 01: x2 subdivision, = 10: x4 subdivision, = 11: x8 subdivision. Current [3: 4] From 00-> 01-> 10-> 11, the current increases in sequence, and the torque also increases in sequence, which can be adjusted according to the actual application. (Be careful to increase the heat sink, otherwise the temperature will be too high and shut down)
