Probably not...
The Beaglebone series appears optimized for use as embedded Linux
controllers. They provide a large number of binary GPIO, SPI, I2C, multiple
UARTs, along with ANALOG inputs and outputs. They have (at least the BBB)
only one USB port. But they tend toward slower single core processors
(ignoring the cryptic PRUs), small amount of RAM. The stand-alone Cloud-9
environment is the "friendly" interface for programming, favoring
Bonescript via node.js (though Cloud-9 does support Python too).
The R-Pi was billed as a cheap Linux computer using Python as the
primary programming language for teaching purposes. It really only has a
few binary GPIO, SPI, I2C -- but no analog I/O. Typically four USB ports.
The newer ones have 64-bit quad-core processors (though the normal OS is
just 32-bit for compatibility across the line) and more RAM -- but lack any
coprocessors. Really meant to be used with an HDMI monitor and local
keyboard/mouse.
Compare:
BBAI: 1.5GHz dual Cortex-A15, 1GB ? RAM, 4 PRU, 4 EVE, 2 DSP, 16GB eMMC,
USB2, USB3?, WiFi
$117+
BBB: 1GHz Cortex-A8, 512MB DDR3 RAM, 2 PRU, 4GB eMMC, USB2
$55+
R-Pi 4B: 1.5GHz quad Cortex-A72, 4GB DDR4 RAM, USB3, WiFi
$55
R-Pi 4B: 1.5GHz quad Cortex-A72, 1GB DDR4 RAM, USB3, WiFi
$35
R-Pi 3B+: 1.4GHz quad Cortex-A53, 1GB DDR2 RAM, USB2, WiFi
$35
The R-Pi foundation seems to release a new model every 12-18 months,
whereas Beagles appear to be targeted for long-term stability (what did I
read, 10 years production life?)
