Zen is a family of Feature Full FPGA development board along with a host microcontroller. Zen is successor to Vicharak's Shrike Family of Dev Boards.
Family Members -:
Zen R4 (Trion4k + RP2040)
Zen R8 (Trion8k + RP2350)
Both the board are pin to pin compatible so much so that they have the same PCB board only the FPGA is different.

| MCU | RP2350B | RP2350B |
| Breadboard Compatible | ✅ | ✅ |
| FPGA ↔ MCU IO Interface | 10 Bit Parallel Bus | 10 Bit Parallel Bus |
| Flash (QSPI) | Upto 128 MB | Upto 128 MB |

| ZEP (Zen Expansion Port) | ✅ | ✅ |
ZEP - ( ZEN Expansion Port ) is a costume extension port standard designed Vicharak for the zen family of FPGA however it will be a open standard that could be ported for your open sources or closed sources project however it has to be with the ZEP name only.
There will a load of Hats for the ZEP to be launched .
