NodeMCU I²C and 1-wire Breakout board

NodeMCU I²C and 1-wire Breakout board

Created by reinhold on 2017-06-05 22:27:30

2 Layer Board - 1.5075 sq in (0.8870in x 1.6996in) / 972.58 sq/mm (22.53mm x 43.17mm)
$5.95 per set of 4 ($3.95 per sq in)

I²C and 1-Wire Breakout board for the NodeMCU with ESPEasy

When using ESPEAsy on the NodeMCU, the I²C pins (D1 and D2) are shared by all devices attached to the I²C bus. Unfortunately, the NodeMCU has only one pin to attach to, so this breakout board provides six sets of V-GND-SCL-SDA pins for six I²C devices to be attached to the D1 (SCL) and D2 (SDA) GPIO pins.

This board also provides six sets of 1-wire pins (G-DATA-V) to attach six 1-wire sensors directly to the board. GPIO-15 (D5) is used as data pin on the NodeMCU.

This board attaches to the left pin row of the NodeMCU (the D0-D1-....-3V pins) and provides one copy of each pin directly next to the NodeMCU.

Bill of Materials

  • JP1 ... 15x1 female pin header (NodeMCU plugs into this)
  • JP2 ... 15x1 male pin header (all NodeMCU pins duplicated, as the original pins are plugged into JP1)
  • JP3, JP4, JP5, JP6 ... 6x1 female pin header (to plug I²C devices in; SCL is D1, SDA is D2); male pins are possible, too
  • JP7, JP8, JP9 ... 6x1 female pin header (to plug 1-wire devices in, data pin is D5); male pins are possible, too
  • JP10, JP11 ... 5x1 male pin header (provides 5 extra sets of V-GND pins)
