dspblok ps-uart - Power Supply Module

The dspblok ps_uart is a 12V to 3.3V power converter and an RS-232 interface board. Power can be provided to a 3.8/1.3mm coaxial power jack or a 5 pin Molex connector

In conjunction with a dspblok ad96k4x board and optional dspblok io-rtc, they are part of a small dspblok mini-stack with a footprint of 60mm x 60mm. The odd shape minimizes the mini-stack height by providing clearance for the dspblok ad96k4x SMA connectors

The UART connections are RXD, TXD, RTS & CTS.

Specifications:

Voltage In:

  • 12VDC, 300mA (Center Positive)

dspblok ad96k Family - I/O Modules

The dspblok ad96k42 & dspblok ad96k22 are small data converter boards that sample at 96k. In conjunction with a dspblok ps-uart board and optional dspblok io-rtc, they are part of a small dspblok mini-stack with a footprint of 60mm x 60mm. Each input and output use SMA connectors to help maintain the small size and provide reliable connections.

These boards were originally designed to work with the now obsolete dspblok 21369. Current systems can use a dspblok 21469 with the pins of JH8 cut off (JH8 didn't exist in the dspblok 21369).

The dspblok 4/2 has 4 audio inputs and 2 audio outputs. The dspblok ad96k22 has 2 audio inputs and 2 audio outputs.

dspblok io-rtc - I/O & Real Time Clock Module

The dspblok io-rtc is a combination general-purpose I/IO expander and an accurate real-time clock board. There are eight general-purpose inputs with 3.3v and ground connections provided.  There are also four onboard LEDs with the ability to connect externally.


In conjunction with a dspblok 21469 and a dspblok 96k4x data converter, it is part of a small dspblok mini stack with a footprint of 60mm x 60mm.
