Features: ForRaspberryPi compute module4 to compute module3 adapter board, an alternative solution forRaspberryPi CM3. CM3+. BasedonRaspberryPi CM4, replacing the CM3 serieswith CM4 solves the problem of oversupply of CM3. Standard onboardCM4 port, supporting the use of quadcoreCortexA72 64bit processor to access CM4 boards, with more powerful performances The onboardstandard CM3 SODIM only needs to be connectedto the originalCM3 ecosystem backplane. Built inBuck Boost DCchip, supporting 3.3V/5V input power. Vehicle mounted ACT can monitorthe working status of CM4 in real-time. Easy installation of CM4, standard CM4 connector on board, support for accessing computing module 4 board Note: computing module 4 is not included in delivery. Specifications: Item: CM4 to CM3 Adapter Size：approx 67mmx46mm Material: Plastic Supporting the use of quadcoreCortexA72 64bit processor to access CM4 boards Package Includes: 1PC CM4 to CM3 Adapter note: Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand. Please allow 0-1cm error due to the manual measurment.
