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 as well as power draw up to 5 V / 3 A 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, even without power. The supercap has, in contrast to a battery, 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
