Key Takeaways
1. The Lyra Pi is a new single-board computer introduced by Luckfox, available in four models and compatible with an LTE modem.
2. All models feature three Cortex-A7 cores running up to 1.2 GHz and a Cortex-M0 core, with RAM fixed at 512 MB DDR3L.
3. The Lyra Pi A has 8 GB of eMMC storage, while the Pi B model uses a memory card and lacks eMMC; both A versions do not have a memory card slot.
4. Connectivity options include two USB 2.0 ports, MIPI DSI support, and two Ethernet ports (max 100 MBit/s); HDMI is not available.
5. The board with the 4G module kit and 8 GB eMMC storage retails for $67, with the Wi-Fi/Bluetooth module available separately for an additional $3.
The variety of single-board computers and development boards has grown significantly in recent times, with the Raspberry Pi leading the pack, now in its fifth generation. Recently, Luckfox introduced a new option called the Lyra Pi, which comes in four different models and can be paired with an LTE modem. The SIM7600G-H-M.2 LTE Cat 4 module supports LTE-TDD, LTE-FDD, HSPA+, GSM, GPRS, and EDGE, making installation a breeze.
Hardware Specs
No matter which model you select, all of them come equipped with three Cortex-A7 cores that can run up to 1.2 GHz, along with a Cortex-M0 core. The Lyra Pi A features 8 GB of eMMC storage, whereas the Pi B model does not include eMMC and utilizes a memory card instead. Notably, the two Pi A versions lack a memory card slot. Both the Lyra Pi A W and Lyra Pi B W are fitted with Wi-Fi 6 and Bluetooth 5.2 capabilities.
Connectivity Options
All models offer 512 MB of DDR3L RAM. While HDMI connections for screens are not available, MIPI DSI connections are supported. The board is equipped with two USB 2.0 ports, and extra USB ports can be accessed through headers. The two built-in Ethernet ports do not reach Gigabit speeds; they max out at 100 MBit/s. The SIM card slot is conveniently located next to the M.2 slot for the mobile modem, and there’s a combined jack for audio output or microphone connection. Like many single-board computers, a color-coded GPIO pin header is included, allowing for easy connection of sensors and actuators via UART.
Pricing Details
The board, including the 4G module kit and 8GB of eMMC storage, measures 85 x 56 millimeters and is priced at $67. However, the Wi-Fi/Bluetooth module is sold separately for an additional $3, which buyers can opt to purchase.
