Revolution Pi Analog I/O expansion module (RevPi Analog I/O)

Using the analog I/O - module RevPi AIO your RevPi base module can be expanded by 4 analog inputs, 2 analog outputs and 2 RTD input channels. This expansion module is connected to your base module by the means of the overhead PiBridge plug. Inputs, RTD inputs and outputs are galvanically isolated to each other. Differential inputs eliminate ground loops.

Analog input range/options: +/- 10 V, 0 – 10 V, 0 – 5 V, +/- 5 V, 0 – 20 mA, 0 – 24 mA, 4 – 20 mA, +/- 25 mA

Analog outputs range/options: 0 – 5 V, 0 – 10 V, +/- 5 V, +/- 10 V, 0 – 5,5 V, 0 – 11 V, +/- 5,5 V, +/- 11 V, 4 – 20 mA, 0 – 20 mA, 0 – 24 mA

The 2 RTD inputs enable temperatures to be measured with high precision from -165°C to +600°C in steps of 0.5°C using common RTDs sensors like Pt100/Pt1000 probes. The probes can be connected directly to the module with 2, 3 or 4 cables.

Just like the digital IO modules, RevPi AIO is protected against disturbances according to EN61131-2 and can be operated between -40 and +50°C ambient temperature and up to 80% relative humidity. It is also protected against static discharges, burst and surge impulses in accordance with EN61131-2 requirements.

The required PiPridge Plug (Item No.: 100204) and a set of 14-pole PCB female connectors (Item No.: 200030) are already included in the scope of delivery of this expansion module.

articles include but are not limited to keyboards, monitors, and mice when used in conjunction with the Compute Module.
• The cables and connectors of all peripherals used with this product must have adequate insulation so that relevant safety requirements are met.

SAFETY INSTRUCTIONS

To avoid malfunction or damage to this product, please observe the following:
• Do not expose to water or moisture, or place on a conductive surface whilst in operation.
• Do not expose to heat from any source; Raspberry Pi Compute Module 4 is designed for reliable operation at normal ambient temperatures.
• Take care whilst handling to avoid mechanical or electrical damage to the printed circuit board
and connectors.
• Whilst it is powered, avoid handling the printed circuit board, or only handle it by the edges to minimise the risk of electrostatic discharge damage.

Raspberry Pi Compute Module 4 (4GB RAM, 16GB eMMC, wireless) (CM4 4GB 16eMMCwifi)

Overview



Raspberry Pi Compute Module 4 harnesses the compute power of the popular Raspberry Pi 4 Model B, bringing it to a smaller form factor suitable for integration into products. Key features include a high-performance 64-bit quad-core processor, dual-display support at resolutions up to 4K, hardware video decode at up to 4Kp60, up to 8GB of RAM, Gigabit Ethernet, USB 2.0, dual camera interfaces, and PCIe Gen 2 x1 interface. The optional dual-band 2.4/5.0GHz wireless LAN and Bluetooth 5.0 have modular compliance certification. This allows the board to be designed into end products with significantly reduced compliance testing, improving both cost and time to market. Either the onboard antenna or an external antenna kit can be used.

Compute Module 4 has optional onboard eMMC of 8GB, 16GB or 32GB.



Specifications:

  • Form factor: 55 mm × 40 mm
  • Processor: Broadcom BCM2711 quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz
  • Memory: 1GB, 2GB, 4GB or 8GB LPDDR4 (depending on variant)


Connectivity:

• Optional wireless LAN, 2.4GHz and 5.0GHz IEEE 802.11b/g/n/ac wireless, Bluetooth 5.0, BLE with
onboard and external antenna options
• Onboard Gigabit Ethernet PHY supporting IEEE1588
• 1 × USB 2.0 interface
• PCIe Gen 2 x1 interface
• 28 GPIO signals
• SD card interface for SD card or external eMMC
(for use only with Compute Module 4 variants
without eMMC)

Video:

• Dual HDMI interface (up to 4Kp60 supported)
• 2-lane MIPI DSI display interface
• 2-lane MIPI CSI camera interface
• 4-lane MIPI DSI display interface
• 4-lane MIPI CSI camera interface

Multimedia:

H.265 (4Kp60 decode); H.264 (1080p60 decode, 1080p30 encode); OpenGL ES 3.0 graphics

Input power:

5V DC

Operating temperature:

0 to +80°C
