Raspberry Pi Competitor Ranks Swell With Orange Pi 4 LTS:
A new version of the Orange Pi, one of the Raspberry Pi competitor boards built around the hexa-core Arm-based Rockchip RK3399 SoC and with a distinctive Wi-Fi antenna, is now available for pre-order, with prices starting from $55, as spotted by CNX-Software.
The Orange Pi 4 LTS (not Long-Term Support, but LTS versions of Orange Pi boards tend to be more compact versions of previous releases) features a six-core processor that sees two Arm Cortex A72 cores matched with four A53 cores and a Mali T860 GPU. There's a choice of either three or four gigabytes of LPDDR4 RAM, and a 16GB eMMC chip can be specified.
The main difference between the Orange Pi 4 LTS and the 4 and 4B boards that preceded it is the GPIO. While previous boards contained 40 pins on their headers, the LTS houses just 26, just like the original Raspberry Pi. And while we can use some Raspberry Pi HATs designed for 40-pin GPIO with the original Pi. Don't expect true GPIO compatibility with the Orange Pi 4 LTS, a quick glance of the GPIO layout shows that I2C is mapped to different pins, effectively breaking compatibility with cards which use this protocol. The audio chip also seems to have been changed, from a Realtek ALC5651 to an ESS ES8316.
