For many add-ons or video analysis, choose 4 or 8 GB.<\/p>\n<h3>What is the processor frequency, 1.5 or 1.8 GHz?<\/h3>\n<p>Current boards run at 1.8 GHz according to the official datasheet. The first Pi 4 revisions ran at 1.5 GHz.<\/p>\n<h3>Which operating system should I install on the Raspberry Pi 4 Model B?<\/h3>\n<p>Raspberry Pi OS 64-bit via Raspberry Pi Imager for general use, or Home Assistant OS, Recalbox or LibreELEC directly, depending on the project.<\/p>\n<h3>Can it be used as a desktop computer?<\/h3>\n<p>For simple browsing and light office work, yes. For many tabs or video conferencing, choose the 4 GB version or higher.<\/p>\n<p><strong>Order with confidence:<\/strong> official, tested products, stock based in France, shipping within 24\/48 h after receipt of payment, free pickup point delivery on orders from \u20ac200, returns within 14 days (with return authorization) and payment by Visa, Mastercard, PayPal, Apple Pay or Google Pay.<\/p>","protected":false},"excerpt":{"rendered":"<ul>\n<li><strong>Quad-core Cortex-A72 1.5 GHz + 2 GB LPDDR4<\/strong> : the best compromise in the Pi 4 range<\/li>\n<li><strong>Dual-band Wi-Fi, Bluetooth 5.0, Gigabit, 2x USB 3.0, dual 4K<\/strong><\/li>\n<li><strong>Ideal for Home Assistant OS, RetroPie, OctoPrint, Plex, VPN server<\/strong><\/li>\n<\/ul>","protected":false},"featured_media":23426,"template":"","meta":[],"product_brand":[393],"product_cat":[22],"product_tag":[],"class_list":["post-31467","product","type-product","status-publish","has-post-thumbnail","product_brand-raspberry-pi","product_cat-carte-raspberry-pi-4","first","outofstock","taxable","shipping-taxable","purchasable","product-type-simple","add-to-wishlist-after_add_to_cart"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/product\/31467","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/types\/product"}],"version-history":[{"count":0,"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/product\/31467\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/media\/23426"}],"wp:attachment":[{"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/media?parent=31467"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/product_brand?post=31467"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/product_cat?post=31467"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/product_tag?post=31467"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
