Hi guys, there are two new portable laser drivers on the block to accompany the Micro FlexDrive. They are called the Micro Boost Drive (same size as the FlexDrive) and the Groove 2 (a little larger). They both can fit into an Aixiz module.
The Micro Boost drive is a boost-only version of the FlexDrive using a different circuit. While the FlexDrive can only boost up to 5.8V, the MicroBoost laser driver can bo st up to 13V from as low as 2.7V input! This driver is designed for running high power 405nm laser diodes from a single li-ion battery or 3 1.5V batteries. It can drive up to 700mA into 7V! It is constructed with a sturdier and slightly larger potentiometer than the FlexDrive for ease of adjustment.
Features:
*2.7-5.5V Input voltage range
*VBatt-13V output voltage range
*reverse battery protection
*open circuit output protection (idles at 13V out when open circuit)
*Sturdy, enclosed adjustment pot
*5 adjustment ranges 65mA to 1000mA
*protective coat over inductor top to prevent chipping
*only 9mm x 12mm !
CLICK:
Also available is a low cost low dropout linear regulator, a diminutive successor to the Groove driver, called the Groove 2. This driver boasts a dropout voltage of 1.2V, nearly half that of other designs. This allows you to use this driver in situations where other linear drivers don't: Drive a red laser diode with 4.5-5V, and a blu-ray with 2 li-ion batts for example. Also, it permits a longer run-time as more battery juice can be used with the laser still bright.
Features:
*Vdiode+1.2V - 12V Input voltage range
*reverse battery protection
*1.2V dropout voltage
*Sturdy, enclosed adjustment pot
*2 linear adjustment ranges 25mA to 600mA
*10mm x 14mm

Let me know what you think
EDIT:
Instructions for PWM modulation (TTL control) of the MicroBoost driver are --> HERE <--.
Note that this also allows you to use a low current switch to turn the driver on and off via the TTL control, without worrying about burning up the contacts on a clicky switch when you switch all the current on and off.
Also note that although it will appear dimmer, the eye damaging capability of the beam will not have decreased much, as it does when it is dimmed via analog means.
The fundraiser is over, thanks to everyone who participated, almost $50 was raised and sent.
In support of a friend in hard times, $2.50 from every sale of the Groove 2 driver from this forum this month of april will be donated to Kenom, the origin of the 'Groove' barrel of this drivers namesake. So stock up on this great, inexpensive universal driver
