Zest_Carrier_Extension

Overview

The Zest_Carrier_Extension board with fully symmetrical connectors provides a simple solution for expanding the functionality of the application with a wide range of specialized Zest daughter boards. It permits to split the stack to facilitate the test and to extend the functionality of the application: for example, simultaneous use of a camera and of PIR sensors, or the implementation of multiple environment sensors.

Power Management

The Zest_Carrier_Extension board comes with two connectors with difference in power management:

  • J1 must be used to plug at least the main Zest Core and the power source for the whole assembly,
  • J2 is powered exclusively from the sources on J1, as its VIN_EN signal is grounded. All power sources from boards plugged on J2 are deactivated.

This is why the J2 side has the following inscription on the PCB: "Daughter boards only / No power source".

Serial / UART Management

Be aware that the signal MD is set to 0 (GND) on J2. Consequently, a Zest Core plugged on the J2 stack has its UART1_TX (pin 69) and UART1_RX (pin 71) signals inverted, to be able to communicate properly with the main Zest Core on J1.

See any Zest Core datasheet for additional information about MD signal ("Mother/Daughter").

80-pins 6TRON header

This table shows how the pinout on Zest_Carrier_Extension corresponds to the pinout on the 6TRON BUS connector (the latter shown in the two middle columns).
