EsPiFF - Development board

EsPiFF is an ESP32^™ board in a Raspberry Pi 4^™ form factor, capable of utilizing nearly every Pi 4 enclosure and HAT. EsPiFF packs an additional punch with wired and wireless Ethernet, an SD card socket, and a RP2040 co-processor. Can't find a Pi for that important project? EsPiFF is the rock solid, low-power Pi alternative you've been looking for.

EsPiff is particularly well suited to measurement, control, and automation projects where the current consumption and heat generation of a Pi or the potential instability of its SD card could be problematic.

Features & Specifications

ESP32-WROVER with 8 MB PSRAM and 16 MB Flash in a Raspberry Pi 4 form factor

Wi-Fi connectivity (requires an external U.FL antenna)

10/100 wired Ethernet via IP101 PHY

PoE header, to use Raspberry Pi PoE HATs. EsPiFF can be powered from a HAT or can power the HAT

Micro SD card socket for storage

Up to 3 UARTs

USB Type-C connector on CH340 USB-UART for programming and powering up to 5V / 3A for power-hungry HATs

40-pin Rasperry Pi header, compatible with all Raspberry Pi HATs

2 kbytes of fast FRAM for permanent storage of process data. (Much faster then EEPROM, for key variables.)

RP2040 co-processor to emulate the Pi on the 40 pin connector, with 8 MB Flash

External realtime clock, watchdog and supervisor for high-availability, 24/7 applications

On-board supercap to keep the realtime clock running for days without power. The supercap a practically infinite lifetime

USB-Host on the USB Type-A connector

BOOT button for the RP2040, to switch between USB-Programming and USB-Host/Device

ESP32 reset button and three user LEDs

HMI: UART controlled displays, programmable with C/C++/Python and LVGL^™

HMI

HMI are revolutionary TFT displays in sizes from 3.9 to 10 inch, what can be mounted on any surface by simply drilling 5 holes. No need for a complicated cutout. The displays can be controlled by a UART interface, and/or can be programmed in C/C++/uPython or JavaScript.

In contrast to other smart/serial displays, the smartHMI can be programmed by the user for any protocol. Examples are direct connection to Modbus, and depend on the message, screen objects can be created at runtime, rescaled, become (in)visible. Based on the powerful LVGL open source library, new screen objects can be created, default behavior overwritten, or extended.

Programmers from PC based GUI application, who used C#, Delphi or Java, will feel soon at home. Thanks to the huge popularity of LVGL, tons of examples can be found in the internet.

Several GUI Form designer for LVGL are available, open source or commercial.

Features & Specifications

Only 5 drill holes needed, no cut-out required

Sizes: 3.9, 4.3, 5.0, 7.0, 10.1 inch

UART interface to be controlled by any host: Arduino^™, Raspberry Pi, ESP32 or any 3.3V UART

Programmable in C/C++/uPython with use of the open source LVGL library^™

shelf kit - upgrade cabinets to electronically monitor RFID equipped parts.

shelf kit

shelf kit enables, to convert standard steel cabinets to intelligent warehouse solution. With a smart shelf kit, a cabinet is able to monitor all RFID equipped goods (non-metal and metal), detects lay ins and take outs, and generates reports about all activities.

shelf kit cabinets can be networked (theoretical up to 254) to a combined solution. A special HMI module with build in card reader is available, to enable access to the goods only for authorized persons.

Features & Specifications

Easy to install in existing cabinets

detect the presence of hundreds of Rain-RFID items within seconds

detect the removal or insertion of each individual Rain-RFID item, and record it

works with non- metallic (laundry, medical) or metallic items

optimized RF and antenna design, no missing item

cabinet-network on RS485 base, in daisy chain configuration.

Uplink to Ethernet network, for central data storage in PostgreSQL database.

configurable reporting system.

MHI module with integrated HF RFID card reader for user authorization. Legic reader modules for higher security are available.

Lock activation (24V, up to 2A) and lock status read.

Up to 4 additional sensor signals (9 to 24V) can be read

additional output (24V, up to 2A) available. For example, for cabinet lights, alarms, cooling/heating.

Matching locks with cables and connectors are available on request.

A typical application is a laundry management system in a hospital:

Depend on how many people use the system, a few to up to a dozen cabinets are equipped with shelf kits, and inter-networked. These cabinet-network is connected via an Ethernet line to the company Ethernet network. In one cabinet, the HMI is installed. One or more drop cabinets are can be added .

Our Reference installation is a German hospital, the Heilig Geist Spital in Freising. Our laundry management system organize the daily take out and returning of the staff laundry, and runs 24/7.
