Projects – Hobbybotics Reflow Controller Quad V1.0

I’ve been working on a redesign of the original reflow controller.  Here are the features for the new board:

  1. Four MAX31855 Type-K Thermocouple interfaces
  2. DS3234 Real Time Clock with battery backup
  3. FT231x USB
  4. XBee or Bluetooth Wireless
  5. MCP23008 I/O Expanders for 2-wire expanded communication
  6. ULN2803 Darlington buffered output relay/SSR control
  7. Internal or external micro SD interface
  8. External LCD I2C interface/input
  9. ATMega 1284P TQFP AVR with Arduino bootloader
  10. 16 MHz Crystal

Take a look at the new board:

 I’ll post more on this project in the coming days.  I’ll be offering this project as a full kit for those who are interested.
