** You will still need TMC2209 drivers, and a 38 pin esp32 (genuine preferred)

Shipping V1.2.1, black PCB

The Jackpot CNC Control board runs FluidNC which is GRBL compatible with extended features and easy configuration and flashing. 

Highlights

• WiFi, Bluetooth, or hardwired capable (esp32), 32bit dual-core 240mhz 
• 6x TMC2209 driver ports7 inputs, 2x 5V outputs, 2x input level (9-24V) outputs.
• One expansion module socket.
• MicroSD card slot.
• WiFi, USB Direct connection, or Bluetooth
• Onboard or external antenna
• Micro USB, or USB-C
• Socket based for easy swapping if anything were to ever go wrong, or you want to quickly change configs. 

Typically populated Jackpot CNC Controller

ESP32-wroom-32 Based control board

• 32bit dual-core 240mhz board.
• WiFi, USB Direct connection, or Bluetooth (rarely used).
• Can have Onboard or external antenna
• Micro USB, or USB-C
• Socket based for easy swapping if anything were to ever go wrong, or you want to quickly change configs.
• 38 pin - ESP32-DevKitC CP2102 - MicroUSB, These seem to be the most reliable.
• 25.4mm header width

9-24VDC

• Current required is a minimum of 19W (24Vx0.8A).
• If you plan on using the high current outputs adjust accordingly.

6x Stepper driver sockets

• This controller is designed for use with TMC2209 drivers in UART control mode only
• Typically, TMC2209 drivers are limited to 4 addresses. This controller uses a CS (chip select) pin for 3 of the drivers to allow 6 drivers to be individually controlled.
• The sockets are labeled XYZABC, but you can use any socket for any axis or motor number. The letters are just for reference only.
• No Stallguard

7x Inputs

• All switch inputs are active low, the LED goes on when ground is connected to the pin.
• They have a 10k pullup external to the ESP32. The signal pin (S) should be connected to the ground pin (G) to activate the switch.
• The 5V Rail is optional and is used for external switches that require 5V.
• The input pins can be pins in the config file to use Normally Open or Normally Closed inputs.

2x Line level outputs (same as input voltage)

• PWM Capable
• The MOSFETs switch to ground. You can use any voltage up to the VMot max as the positive, as long as it uses the same ground reference.
• Can be used to drive 2.5A continuously before they overheat. You can use them intermittently up to 3.5A.
• They can be used with inductive loads (solenoids, relays, DC fans/motors)

2x 5V outputs

• PWM Capable
• These will source and sink about 25mA each.
• Most commonly used for tool SSR’s and Lasers.
• See the “Spindle” section of the FluidNC wiki for common uses.

1x Expansion Module socket

• 6 PACK expansion module source
• Buy Them
• This should be able to use any CNC I/O module. Use an 11mm standoff or a 3D printed support in the mounting hole provided.
• These Modules can be just about anything you need, pendant, more inputs, outputs, relays, spindle, VFD, Servo, OLED…

1x MicroSD card slot

• larger than 2gb needed
• Fat32
• 30 character or less file names, 100 character or less file location

Firmware

• FluidNC
• Text based config file for simple firmware edits.
• No compiling to flash a board or change the configuration.
• ~100% GRBL compatible
• ESP3D-UI
