The "atomic pi" looked good at first and then we foubd they were just surplllus junk that will never be suported in the long term.
Here is a NEW product that has has a huge company suporting it. In fact, they were smart to get there support and documentation in order some months before the product was released. STM has a hybrid ARM hybrid A and M chip. The A side of the chip can run Debian Linux. They have their own version and I think real-time support for it and the M side of the chip is the normal STM32F microcontroller. This is a little like the Ti chip in the BBB that has PRUs but the M4 is quite a lot better suited for machine control because of the attached peripheral hardware. It can generate pulses and decode quadrature encoders all inhardware with no CPU cycles. The chips themselves are selling for about $15 so a user level retail product might be cheap. STM has a history of selling subsidized development board at lowe cost. These will be sold in large numbers The first boards are on sale now. The lowest spec one has pretty good performance including gigabit Ethernet and HDMI video for $70. For another $30 they add a phone-sized touch screem WiFi and Bluetooth. Read the specs here, very impressive for a low-cost chip https://www.cnx-software.com/2019/02/21/stmicro-stm32mp1-cortex-a7-m4-mpu/ I have always thought the best machine controller would be some combo of Linux with a uP and then the user interface would run on a tablet with a touch screen with an option to use multiple screens This would enable that kind of design. The peripheral hardware, (that would be quadrature decoders, hardware PWM and analog I/O) would make this as fast as an FPGA based controller but it runs Linux on the same chip so the communications is easy On top of all this STM is very supportive of developers and maintains compilers and IDE and the Linux OS images.
