CATENA 4710 – LORAWAN BASED FEATHER-COMPATIBLE FPGA BOARD WITH RISC-V CORE
With the increase of high integration programmable chips, FPGAs are getting more and more popular. FPGAs has been traditionally known to be generally complex, but a new line of FPGAs have been showing some promise and that is believed that will help increase their popularity. Tiny FPGAs are the next promising thing, they are low-cost FPGA boards in a small form factor, and generally easy to use.
MCCI Corporation a USB System expert who has also been venturing in the line of IoT solutions has recently tipped a Catena 4710 FPGA board which is a “feather-compatible FPGA board” that can easily fit into your pocket and comes with a RISC-V Core with support for Lora Networks.
Although this product seems to been put together by Terrill Moore, CEO of MCCI, the design of the product was done by Velmurugan and Veeralakshmi. The board is based on ICE40 UltraPlus FPGA and runs in a soft RISC-V core. On the bottom side of the board, it has Semtech SX1276 and HopeRF RFM95W RF wireless transceivers attached to it.
The Semtech SX1276 (SX1276/77/78/79) transceivers feature the LoRa® long range modem that provides ultra-long range spread spectrum communication and high interference immunity while minimizing current consumption. With the Semtech chip, LoRaWAN is possible on the board allowing a smooth point to multi-point networking. It also has a USB micro B port along with a battery and an antenna connector.
The device is also sensor ready; it comes with an environment sensor – the BME280 sensor which enables to sense temperature, pressure, and humidity. Also, it has a light sensor, a color sensor, an accelerometer, and a possible microphone unit. There’s also an antenna connector at one end, as well as a USB and battery jack for charging and plugging Li-Ion batteries.
