 ## Firmware
 
 * [**candleLight_fw Entrée fork**](https://github.com/tuna-f1sh/candleLight_fw) - [[BIN DOWNLOAD]](./bin/entree_fw_101.bin): Default firmware shipping with Entrée. Works with [Linux SocketCAN](#linux-socketcan) and the [Cangaroo](#cangaroo-gui) GUI. Includes support for configuration of the on-board STUSB4500 USB-C controller and DFU without setting DIP switch.
-* [**PCAN CANtact**](https://github.com/moonglow/pcan_cantact): Open source _PCAN_ compatible firmware\*; works like a PCAN USB adaptor with the PCAN software suite and python-can module. Does not include USB-PD configuration or DFU. \*Not supported or endorsed by _Peak System_.
 * [**cantact_slcan**](https://github.com/normaldotcom/cantact-fw): slcand is a USART CAN daemon for Linux, which emulates a CAN network socket over USART. The pre-cursor of the candleLight_fw and gs_usb driver, it offers no real advantage since it is still over USB as a CDC. I've found it to drop frames at common bus rates and so do not recommend it. USART pins are exposed however if one wishes to play with slcan over physical USART. A virtual network interface can be created: `sudo slcand -o -s8 -t hw -S 3000000 /dev/ttyS0` and then used like a [SocketCAN](#linux-socketcan) interface.
