Ethernet Plug

January 22, 2015 |   |  Comment  |  TaaraNode

Ethernet Plug is small ENC28J60 based Ethernet controller board for TaaraNode and JeeNode microcontroller boards. Ethernet Plug operates entirely on 3.3V and has a on-board LDO regulator or DC/DC converter. The board can be powered either from microcontroller board it is attached to or via Passive POE. If the DC polarity from the PPOE may be issue there is also place for bridge rectifier which is bridged by default.

Features

  • Ethernet Controller: Microcip ENC28J60
  • Passive POE: default
  • Passive POE polarity auto-sense: optional
  • Supply voltage: 5-16 V DC (LDO, default) or 4.75-34 V DC (DC/DC, optional)

1-Wire Plug

January 22, 2015 |   |  Comment  |  1-Wire, TaaraNode

1-Wire Plug is 1-Wire to i2c bus converter board based on Maxim DS2482-100 Single-Channel 1-Wire Bus Master chip. It is used to off-load the time critical 1-Wire waveform generation from the MCU to the 1-Wire Bus Master to achieve error free operation with longer 1-Wire bus situations. Board header layout is compatible with TaaraNode and JeeNode microcontroller boards. There is on-board 5V LDO regulator, strong pull-up mosfet and the level converter for 5V to 3.3V i2c interface.
