What’s new
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
