The pi zero 2 is the latest iteration of the pi family, and its here to replace the pi zero w

The main change is the "SIP" : A RP3A0 system-in-package (SiP), integrating a Broadcom BCM2710A1 die with 512MB of LPDDR2 SDRAM

In practice this means it's cpu almost 5x faster than the pizero w but the LPDDR2 memory runs at the same speed and the size (512mb) hasn't been increased either


The Pi zero 2 W uses the old arm hf kernel by default, to switch to the 64 bit kernel you have to set* :


*currently this doesn't work and you first need to run  sudo rpi-update before setting arm_64bit=1 or your pi won't boot


The pi zero 2 W runs its 4-core ARM Cortex A53 CPU at a conservative 1 GHz and its  LPDDR2 SDRAM at a conservative 400 MHz

This means the defaults in /boot/config.txt would be the following if they where set  :


Peak power consumption at full load with these settings is around  0.51A**

My current pi zero 2 W settings are  :


And it runs without any issues and its power consumption is 0.60A at peak**

If you need more speed 1200Mhz on core kinda works:


but it seems to use a lot more power 0.65+A** and drops my supply voltage bellow 4.5v (that's probably just a cable/ power supply issue doh)

** all measurements are done with a dinky usb power monitor so take them with a grain of salt

Hardware info

To get an overview of the current hardware settings create a file called

and paste :


for src in arm core h264 isp v3d uart pwm emmc pixel vec hdmi dpi ; do 
    echo -e "$src:\t$(vcgencmd measure_clock $src)" ; 

for id in core sdram_c sdram_i sdram_p ; do 
    echo -e "$id:\t$(vcgencmd measure_volts $id)" ; 

vcgencmd measure_temp

vcgencmd get_mem arm
vcgencmd get_mem gpu

make it executable with chmod +x and run it with ./

it wil return something like:

arm:	frequency(48)=600000000
core:	frequency(1)=250000000
h264:	frequency(28)=0
isp:	frequency(45)=0
v3d:	frequency(46)=270000000
uart:	frequency(22)=48000000
pwm:	frequency(25)=0
emmc:	frequency(50)=200067000
pixel:	frequency(29)=338000
vec:	frequency(10)=108000000
hdmi:	frequency(0)=0
dpi:	frequency(4)=0
core:	volt=1.2063V
sdram_c:	volt=1.2000V
sdram_i:	volt=1.2000V
sdram_p:	volt=1.2500V

the frequency's are in hertz so to get the frequency in mhz divide by 1000000
