TechInsights Teardown: Pico 4 headset
Virtual reality (VR) continues its growth path as more content becomes available through games, movies and other playable content.
Then there’s the metaverse, which may or may not be a thing that is still happening depending on who you ask and who is investing in the so-called next big thing in shopping, art, fashion and entertainment. The main driver for the metaverse will be both VR headsets and augmented reality (AR), which uses both real world and virtual images to create a singular platform.
The fourth generation of Pico Technology’s VR headset, called the Pico 4, is the latest for gaming and the metaverse. The headset includes an applications processor from Qualcomm and main memory from Samsung. Additionally, there are TFT displays and megapixel cameras that are included in the platform.
The following is a partial deep dive into the VR headset from Pico Technology performed by TechInsights.
- 2.6-inch TFT w/ chip-in-glass, 2160 x 2160 pixels
- 8 GB LPDDR3X SDRAM
- 16 MP BSI CMO
Released: September 2022
Target market: Consumer electronics
The main board is the Pico 4 VR unit contains the main components needed to operate the headset such as the Qualcomm octa-core Snapdragon XR2 applications processor and Samsung’s 256 GB TLC V-NAND flash and 8 GB mobile LPDDR4X SDRAM. Other components inside the main board include:
- Four-channel ESD protection from Nexperia
- 5 GHz Wi-Fi front-end module from Qorvo
- DPT RF switch from Maxscend
- Bluetooth 5.0 LTE/Thread/Zigbee SoC from Nordic Semiconductor
- AWINIC’s display power management
- OmniVision’s camera power management IC
- SG Micro 5 V step-up DC-DC converter
- Arm 32-bit Cortex-M4 MCU from GigaDevice
- Synchronous boost controller from Southchip
The sensor board includes numerous microelectromechanical systems (MEMS) and sensors used in the operation of the Pico 4 headset. This includes the AKM Semiconductor three-axis electronic compass and the six-axis MEMS gyroscope and accelerometer from TDK-InvenSense.
There are two controller boards with the Pico 4 VR headset system for the left- and right-side controllers that are used to manipulate the environment in the virtual world. The main electronic components found on these boards include:
- Nordic Semiconductor’s Bluetooth 5.0 LE/Thread/Zigbee SoC
- SG Micro’s 5 V step-up DC-DC converter and load switch
- AWINIC’s haptic driver
- Onsemi’s temperature sensor
- Azoteq’s capacitive proximity controller
