Know The Board – FiPy

It’s every developer’s dream to have multiple communication technologies in a single board. We started our journey from 8051 development board which has serial, wired communication technology to ESP8266 which has wireless communication technologies like WiFi and BLE.

Here comes our new “Hero” FiPy which comes with WiFi, Bluetooth, LoRa, Sigfox and dual LTE-M (CAT-M1 and NB-IoT). As well as the FiPy gives access to global LPWAN networks.

What’s on the Board

Ref : pycom.io

FiPy comes with dual core ESP32 SoC which includes WiFi and BLE . Additionally it has a 4MB RAM , 8MB Flash Memory , LoRa , Sigfox and LTE (CAT M1 and NB1) .The Network processor handles the WiFi connectivity and IPv6 Stacks , so that the main processor is free and available to run user’s application .

An extra ULP(Ultra Low Power)-coprocessor that can monitor GPIOs, the ADC channels and control most of the internal peripherals during deep-sleep mode while only consuming 25uA. This is one of the main advantage of FiPy that makes this board compatible for IoT applications. When you need to run your board run for more than 10 Years with a single battery.

FiPy has separate external antenna connectors for WiFi/BLE , LoRa/Sigfox and LTE . WiFi and BLE doesn’t required an external antenna unless you specify it. Where as LoRa/Sigfox or LTE its recommended to use antennas always when you use it.

The nano sim socket comes under the board . The board has an LED indicator as well as a reset switch which normally comes with ordinary boards in the markets .

Interfaces

FiPy comes with 22 GPIO ports, yeah that’s a great number. It has 2 Serial ports , 2 SPI interfaces, I2C and micro sd support. The main thing about FiPy is that it has two 8 bit ADC and two 8bit DACs.

FiPy has two 64 bit timers with PWM up to 16 Channels. The incredible board also supports DMA(Direct Memory Access) on all peripherals.
