swatch - HavenTechnik

Swatch utilises a composite header which combines power requirements and the establsihed protocol which are used.

When creating POC code, the need is for simplicity and ease of integration for the project actual going forward. Swatch provides a common interface which enables access to standard I/O, RS transmission lines, I2C, SPI and analog lines.

Swatch's space saving, vertical attitude when placed in board enables multiple units to be connected in "back-plane" style.

DTH-11: Measure RH% and Temperature
1-Wire: Connect Dallas 1-wire devices
MQ: Install any of the MQ sensors to measure 02, N02, LPG, Air Quality
RS-485: Connect a daisy chain of boards
Thermo: K Type Thermocouple conversion module

Launching November 2019, the first four of the series are available along with code samples.

DHT-11

RS-485

The RS485 Swatch enables communicatio on the RS485 BUS.

Thermo

The Thermo Swatch is designed to work with a K-Type thermocouple. This enables temperature measurement from 0'C to 400'C.

MIC-PSU

The MIC-PSU is based on the MIC29302 Linear regulator, is an alternative to a BuckConverter. The MIC-PSU has low to no noise, but offers relatively the same voltage and current output. The unit can be adjusted from as low as below 2Vdc, to up to 16VDC with a 3 Amp sustained current output. This makes the MIC-PSU ideal from GSM projects and other embedded applications where either high current at low DC voltages is required or instantaneous high value output current is needed.
GSM and WIFI applications would fit into the scope of the new devices range of applications, as both these twoo fields have low nominal operating current, however require spontaneous high current. If the communications module doe snot recieve the required value, the device can shutdown or reset. The MIC-PSU therefore offers an ideal alternative for these types of applications.
MIC-PSU is easily integrated into existing projects by replacing the existing power supply, or by being the primary choice. Learn more . . .
