Raspberry Pi DAQ HATs deal with analog

Contec has added three new RPi HATs to it DAQ-oriented CPI Collection for 12-bit, 8-ch. remoted analog in, 16-bit, 2-ch. remoted analog out, and 32-bit Up/Down counter. There may be additionally a DIN-rail package for its HATs and a few latest “DX” Jetson edge AI techniques.

We missed Contec’s April announcement of its CPI Collection HAT Dimension Playing cards for digital acquisition (DAQ), having forgotten totally concerning the Japanese embedded agency, which was based in 1975. We had to return to our LinuxDevices archives for our final Contec report from 2011, about an Atom D510 primarily based BX-956 embedded laptop. We heard about their newest spherical of CPI Collection Raspberry Pi HATs from this Nov. 1 MarketScreener announcement. Farther under, we additionally have a look at some latest DX-branded embedded computer systems primarily based on Jetson Nano and Xavier NX.

The three new CPI Collection HATs for the Raspberry Pi deliver the entire as much as 10 and supply some analog I/O to enrich the earlier boards’ digital enter and output capabilities. The stackable HATs are designed for manufacturing facility automation and measurement management functions, including as much as 8x stacking functionality to the HAT spec for “multi-stage connectivity for general-purpose usability.”

The HATs present push-type terminal blocks, -20 to 60°C assist, and an API that's appropriate with Python and PC growth playing cards. A freely downloadable Linux driver (API-TOOL for Linux) comes with pattern Python and GCC applications.

As proven within the chart above, the primary spherical of CPI HATs launched in April present varied sorts of 8-channel and 16-channel remoted digital inputs and outputs, in addition to relay outputs. There may be additionally a CPI-RAS module with energy provide I/O, watchdog, RTC, HW monitoring, LEDs, and DIO.

The three new HATS are as follows:

  • CPI-AI-1208LI — 12-bit, 8-ch. analog enter with bus isolation and a number of enter vary and kinds
  • CPI-AO-1602LC — 16-bit, 2-channel analog output with inter-channel isolation, and assist for varied voltage output ranges and present output sorts
  • CPI-CNT-3201I — 32-bit Up/Down counter with opto-coupler bus isolation

There may be additionally a brand new CPI-DIN01 DIN-rail adapter package designed to deal with a Raspberry Pi SBC geared up with a number of CPI HATs. The package mounts on a 35mm DIN rail.

Within the April announcement, Contec stated it was additionally planning to introduce a temperature sensor enter HAT. Different stackable Raspberry Pi DAQ HATs embrace MCC’s MCC152 voltage output and digital I/O HAT and Sequent Microsystems RPi add-ons resembling its Mega-RTD HAT for exact temperature measurements.

DX-U12x and DX-U11x Jetson edge AI techniques

Contec gives an in depth line of DAQ techniques, industrial computer systems, panel PCs, and different embedded techniques. Many if not a lot of the techniques are provided solely with Home windows, however during the last yr, the corporate has launched 5 Jetson-based techniques that run Ubuntu.

In July, Contec announced three DX-U12x edge AI techniques that run Ubuntu 18.04.5 LTS and Nvidia’s JetPack 4.4.1 on the hexacore Jetson Xavier NX with 384-core Volta GPU, 8GB LPDDR4, and 16GB eMMC. The techniques are geared up with 2x GbE, HDMI, DP, USB 3.2 Gen2, USB 2.0, and micro-USB 2.0 OTG ports.

The DX-U12x techniques are additional geared up with a microSD slot, 4-in/4-out DIO, an RTC, and M.2 B-key and E-key slots. The -20 to 60°C tolerant system has a 12-24VDC enter.

The DX-U1200-3E0211 and dustproof DX-U1210-3E0211 measure 160 x 92 x 43mm whereas the 160 x 92 x 75mm DX-U1200P1-3E0211 provides a PCIe x1 slot, in addition to inside GPIO and MIPI-CSI-2 “for analysis.”

Final December, Contec introduced two DX-U11x techniques that run Ubuntu and Jetpack on the lower-end, quad-core Jetson Nano with 128-core Maxwell GPU, 4GB LPDDR4, and 16GB eMMC. The techniques provide the identical options because the later DX-U12x, besides that there's a USB 3.0 port as a substitute of USB 3.2 Gen2. Along with the usual, 160 x 92 x 44mm DX-U1100-2E0211, there's a 160 x 92 x 75mm DX-U1100P1-2E0211 mannequin with the identical PCIe x1 slot, GPIO, and CSI-2 interfaces discovered on the DX-U1200P1-3E0211.

Additional info

Contec’s three new CPI Collection HATs and DIN-rail package can be found now together with the opposite seven CPI Collection HATs, with pricing unavailable. Extra info could also be present in Contec’s announcement and in its product pages for the CPI-AI-1208LI, CPI-AO-1602LC, CPI-CNT-3201I, and the CPI-DIN01 DIN-rail package.
