The last LeMaker product I reviewed was the Banana Pro back in July 2015, and if you thought the Chinese-based electronics company had finished drawing inspiration from the Raspberry Pi Foundation when it dropped the ‘Banana Pi’ branding, the Guitar will soon disabuse you of that notion. Based in no small part on the Raspberry Pi Compute Module, the Guitar serves to fill a gap in the market, being an affordable computer-on-module (COM) in a 204-pin SODIMM form factor.
So far, so Compute Module. However, while the Raspberry Pi Foundation has been slow to replace the Compute Module’s aging single-core ARMv6 BCM2835 system-on-chip processor, the Guitar boasts a quad-core ARMv7 chip running at up to 1.3GHz, sitting alongside a PowerVR SGX544 graphics processor. There’s also 1GB of DDR3 memory included on the SODIMM module itself, along with a combined audio and power management unit and 8GB of on-board flash storage. That’s a lot of hardware, and the footprint suffers for it.
