- napolux 4y agoSame. Dunno what to buy
- gorkish 4y agoUnless you know exactly why you have a strong preference for any of the others, and availability concerns notwithstanding, I'd suggest the Pi CM4 model based on the larger ecosystem surrounding the board.
- giobox 4y agoGood advice, but worth noting the CM4 isn't included and there are a surprising number of CM4 variants now. They only advise one specific model number (104000 - the 4gb ram no onboard storage CM4), clarification on this would be good too.
- gorkish 4y agoThe advice for the no-storage CM4 is because the modules are designed to work with either onboard eMMC or external SD, but the interface is shared so you have to pick one or the other. If you use an eMMC CM4 the sd card slot would not function, but it should otherwise work. The 8GB ram CM4 would also be fine of course. (It's possible through a different hardware design to support a secondary, slower sd card interface for an emmc cm4 via the SDHOST peripheral connected to some GPIO pins, but the pi cant boot from it)
- emdashcomma 4y agoI believe the difference is the core module included, where (CM4 = Compute Module 4): RPI-CM4 Lite: Raspberry Pi CM4 104000 lite (ARM Cortex-A72 quad-core, 4GB LPDDR4, WIFI 2.4 GHz, 5.0 GHz IEEE 802.11 b/g/n/ac wireless + Bluetooth 5.0, BLE) A-06: A-06 Core module (ARM64-bit Dual-core Cortex-A72 + Quad-core Cortex-A53, Mali-T864, 4GB LPDDR4) A-04: A-04 Core module (ARM64-bit Quad-core Cortex-A53, Mali-T720, 2GB DDR3) R-01: R-01 Core module (RISC-V 64bit Single-core RV64IMAFDCVU @ 1.0GHz, No GPU, 1GB DDR3)
- wilsonnb3 4y agoYou can swap out the core modules as well, at least on their previous products. Some of them require an adapter that you have to purchase separately.
- sigmaris 4y agoThe actual SoCs used on each type of core module are somewhat well hidden (no mention on the main website as far as I can see) but can be found through a bit of research: RPI-CM4 Lite: Broadcom BCM2711 A-06: Rockchip RK3399 A-04: Allwinner H6 R-01: Allwinner D1
- forty 4y agoThanks. I wonder why they would hide it?
- mid-kid 4y agoDoes this mean that only the CM4 version has wifi? What about the LTE support they mention on the front page?
- numpad0 4y agoCarrier board has some sort of ESP32-esque WiSoC, plus LTE daughter board is listed alongside the products. I can't find which exact SoC is being used though...
- Farbklex 4y agoSame. Took me a while that there is a Raspberry Pi 4 Compute Module version and multiple versions with other ARM boards with different specs. Still don't know what the best board is for my use case. I would like to have a dumbed down environment which is optimized for this handheld format and lets me start some editors and fantasy consoles from a menu.

Yes to that adding some instant on/off/hybernate . Would be great to capture ideas when they come and not wait for the thing to boot and make other decisions. Something like a dedicated device but configurable for other tasks.
